honda nav upgrade in a non-nav vehicle
 

hi,
I have recently bought a used 2003 honda accord ex v6 AT and already put 5k miles on it in 2 months. I am simply loving it. I have plans to upgrade the radio to a navi+radio. I am hoping to install a honda factory navigation unit. I have already bought the navi head unit(that goes into the dash) and the dvd unit(trunk). I need the harness wires. Would someone be so kind as to let me know if I can get it at a non-honda store? The honda people are ripping me off. Also will the installation require a new dash or can I just remove my existing radio unit and replace it with the navi unit coz they pretty much look the same. Also can I get it installed at circuit city or best buy or some other store rather than the honda dealership???? Lastly, IS THE CODE FOR THE NAVIGATION UNIT SAME AS THE CODE FOR THE RADIO, THE GUY WHO SOLD THE UNIT GAVE ME A 4 DIGIT CODE AND I HAVE BEEN HEARING THAT THE CODE IS A 5 DIGIT number? Can someone with a navi accord confirm if the code for the navi is 5 digit or 4 digit.
thanx.

I can't help you with harness/wires but I can tell you that NAV uses 4 digit codes.

You still need the upper vent panel and sub display. There is a guy who will make you a wire harness on eBay for $600 -- at this point I'm still researching how to make one by myself. I will be posting a DIY on my website if I ever figure it out. I do know the guy makes customized connections because its near impossible to find the connectors Honda uses for the head unit and dvd ecu in order to make your own wiring harness.

RE: honda nav upgrade in a non-nav vehicle
 

jhowkins, did you get to the DIY? Any updates?

RE: honda nav upgrade in a non-nav vehicle
 

I'm progressing along... I've got the head unit, upper vent panel w/ sub display so far. Plus, I've also got a few service manuals the Honda dealers use, but I still need one more to complete the set of 3. Also, I'm waiting for a guy to send me to DVD navigation ECU which I've already paid for, but he is taking his sweet time sending it!!!

I'll be adding info about pin-outs, connectors, how to make the wiring harness once I've learned how to do it myself... and finally, how to install the whole thing into your non-navi 7th gen accord!

Check it out at: http://www.geekeng.com

I welcome your comments, so feel free to visit often as I complete this DIY.

Thanks for your interest... its too bad no one did this sooner, would've saved me some time and moolah.

RE: honda nav upgrade in a non-nav vehicle
 

CAN ANY ONE PLS TELL ME HOW TO RE-SET THE NAVIGATION SYSTEM (GPS). I HAVE A JAPANESE DOMESTIC MODEL ACCORD 03. THE CLOCK SHOWS JAPANESE TIME ONLY. I TRIED TO RE-SET BY PULLING OF THE BATT TERMINALS AND PUT IT ON AGAIN. BUT IT SHOWS 1:00 O CLOCK FOR SOME TIME AND JUMPS BACK TO JAPANESE TIME AGAIN.

PLS TELL ME IS THERE ANY WAY TO SOLVE THIS ONE.

Note:
When the battery is disconnected, the internal GPS clock is reset to '0:00'. The clock will reset to the correct time after the system finishes GPS initialization.
Something you should try:
Map Matching
This part of the initialization matches the GPS coordinates with a road on the map screen. To perform this part of the procedure, ensure that the navigation system is displaying a map. Check the 'GPS' icon in the upper left corner of the screen, it should be 'Green' when the vehicle is parked outside, with the correct color labeled DVD installed in the navigation unit. Drive the vehicle on a mapped road shown on the map screen. Do not enter a destination at this time. When the name of the current road you are driving on, appears at the bottom of the screen, the entire procedure is complete. Your system is now ready to use.
Also:
Audio-HVAC Subdisplay/Clock Has Wrong Time

NOTE: This applies to ’03–05 Accord EX-Ls and EX V6s with the navigation system.

Is the time on the audio-HVAC subdisplay/clock not matching the time on the audio-HVAC display module? If this is the case, you need to synchronize the two clocks. Here’s how:
1. Press the SETUP button on the display
module. From the Set-up Screen, select
2 or 4. Then select Time zone/clock.
• If the time is off by exactly 1 hour, check
if the daylight savings setting is on or if the
time zone setting is right for your area.
• If the Set-up Screen time matches the
subdisplay/clock time, but both times are
wrong, touch the Reset button on the
screen. This clears any adjustments that your
customer might have made with the + or -
buttons from the Clock adjustment screen.
• If the subdisplay/clock time doesn’t match
the display module time on the Clock
adjustment screen, there could be a
communication problem. Go to step 2.
2. Go into the diagnostic mode (see section 22
of the 2003–2005 Accord S/M for details).

>>> Here is the process for diagnostic mode:

Start-up procedure and Diagnosis Menu There are two ways to enter the diagnostic mode: Connect the SCS connector to the navigation service connector located in the trunk. Turn the ignition switch to the ON (II) position. The display will go directly to the diagnostic menu screen shown below. NOTE: When finished troubleshooting, make sure to remove the SCS connector.[/ol] Turn the ignition switch ON (II). Use the navigation display hard buttons as described below:
A. If the battery has not been disconnected, then press and hold the 3 buttons (Menu, Map/Guide, and Cancel), and keep them pressed for about 5 seconds. The display screen will go directly to the 'Select Diagnosis Items' menu shown below.
B. If the battery was disconnected and reconnected prior to this test, hold down the Menu and Zoom Out buttons at the 'Code' or 'GPS Acquire' screen. The display will go to the 'Navi System Link' screen. Push the joystick to go to the 'Functional Setup menu,' then touch the Return icon to get to the 'Select Diagnosis Items' menu.
NOTE: This only allows access to the diagnostic screens. All other navigation functions are disabled. After the display changes to the Select Diagnosis Items menu, select the item you want to check and the diagnostic will start. To return to the previous screen, select 'RETURN'. Navi System (Link) F-CAN (System link) B-CAN (System link) Monitor Check Unit Check Car Status GPS Information Yaw Rate Tire Calibrate Functional Setup Version[/ul][/ol]>> End diagnostic mode procedure ***this information cost me $20 !

Select Functional Setup, and then H/U Time
Send. Make sure you’ve selected ON, then
touch the Set button. You may need to keep
doing this last action until the H/U time send
completes. If the two clocks still won’t sync,
then go to step 3.
3. Check the 10P connector between the
subdislay/clock and the display module. Look
for loose terminals, and check for any opens
or shorts in the wires. Repair the connector if
needed.

Stevent...

I saw the v6 forum earlier. I found the information to be disorganized and for the most part - incomplete.

My objective is to gather all the information together about the complete install, including the construction of the wire harness with not just pin-outs, but also schematics, wire lengths, where to buy parts, how much to expect to pay, where to route the wiring harness, which connector does what, what the difference between the premium and basic navi head units is, what the part numbers from honda is for parts like, the voice command controls on the steering wheel and the microphone, walkthroughs for takeaparts and basically a complete resource for anyone with a 7th gen accord looking into replacing their radio for a navi. I might even look into what it takes for someone to do the non-dual climate to dual climate swap, which is crucial for adding a navi --- that would come waaaay waaay later. There is alot to know to do this that is found easily in the ETM's, but who wants to go buy an ETM if the entire walkthrough is publicly available? My plan here is to do this swap on my car, and document it completely to save others money and headache.

......but thanks for mentioning it.

I'm still on the hunt for OEM connectors for the system -- I would prefer to avoid modified parts if at all possible. I'm in the early stages of contacting JST, KOWA SEIKI, FURUKAWA, YAWAKI and a few other connector companies I happen to know have or had a relationship with Honda.

If anyone has any information about how to obtain Honda OEM/Aftermarket connectors that fit the navi head unit and dvd ecu , please PLEASE post them here. I am looking for the 10p connector for the sub-display and pretty much every connector that attaches to the dvd ecu in the trunk.

^ there was a thread where the guy had the step by step diy but I cant seem to find it anymore ever since the upgrade.

RE: honda nav upgrade in a non-nav vehicle
 

Yeah... here is the link:

The guy has some good info, but its missing the most important part - the procedure. He's missing how to disassemble the dash, route the wires, and mounting the unit in the trunk. Assuming you don't have a navi, you wouldn't know how to do these things without hours of research and a few honda manuals to confirm you're wiring everything correctly. I will attempt to make this install easier than ever before. At least that is my intentions here. Perhaps a PDF with pictures and part numbers, etc is in order.

If you CAN find a complete DIY install, please let me know. So far no one has put any elaborate how-to together yet. I'm sure 7th gen accord owners would appreciate one.

RE: honda nav upgrade in a non-nav vehicle
 

i found one but the pictures are missing and it is essential to the install though.

RE: honda nav upgrade in a non-nav vehicle
 

I have been meaning to add this comment, but I've just been too busy lately.

I found a very promising manufacturer who makes at least a few of the connectors for the wiring harnesses.
After nearly a month of research and completely disassembling a navigation dvd ecu, I can finally take a break from my seemingly endless search for these unknown pieces.... I have to laugh now that I have found the company though... Honda wasn't even able to tell me. I'm sure someone somewhere within the company knew all along, but the average guys at the dealers, etc didn't have a clue where to send me to start looking.... me 1 - honda 0

RE: honda nav upgrade in a non-nav vehicle
 

This is more of an update on my progress than anything else... I haven't really posted anything for a month or so.

Back in October, I located a manufacturer who makes *some* of the connectors used on the stock navi for 7th gen accords... and several other acura and honda models. At the time I wasn't aware the there were actually two different brand of connectors used, so I waited for a contact to confirm they didn't carry the correct connectors to fit every hole in the back of the navi. Now, some 2 months later and several failed attempts to have anyone tell me their sources, I have identified the other connectors I was previously unable to identify. Its less than a week away from Christmas, so I guess I could call this "find" an earlier present. So how does this affect you, you ask? Well, if you are interested in doing a stock navi install on your car, you'll be pleasantly surprised to find it will cost you over $10,000 at the dealer, roughly $2500 (complete kit) off eBay, and if you're lucky- $2000ish if you buy all the parts individually off eBay at smokin' prices. My intention was to document my progress as I fought my way though obtaining the correct parts so that you wouldn't have to spend nearly as much time or money as I did. My payoff? Hopefully some of you will appreciate the months of effect I've poured into this project so far, and give me credit where credit is due. I know I'm not the first one to do this, but I'll be the first one to document HOW to do this, and more importantly, how to obtain the parts at the best deals, where to obtain them, and how to put them all into your car once you have them.

So if you are thinking about doing a stock navi install, take a few minutes and read my website... soon I will have all the info you need as promised, but not before I complete the task myself - afterall, you wouldn't take my advice if all I did was talk the talk and fail to walk the walk.... right?

Happy Holidays fellow Honda Accord owners!

Jhowkins... well i guess its been 3 years and your website is no longer available... anyone here knows or have the info?

The real deal all-inclusive

-The back up camera is $100 more for 06-07, and $200 more for 03-05 system.
-The video input is $100 more.
-The system for the single climate Accord is $200 more.

I got in contact with him by email and over the phone and since he wouldnt budge for the harness price, I bought the harness plugs from him. Now i need to make the harness with the wiring schematics he supplied me but im having a bit of a hard time understanding it and I also don't know where to get the sub display air vent. Any idea where i can buy the sub display air vent?

Thanks for the feedback/update. This information helps us all.

"Sub Display" meaning the monitor that is high on the dash? Hondapartsdeals will sell the OEM part or give you the exact Honda model number with which you can look on ebay.

DVD based navigation has the drawback of needing new DVD's every couple of years, as roads change. The GPS is usually positioning, not maps. Can you buy updated maps? What year maps do they give you?

Go to www.hondanavi.com, they are $185 for latest butr usually go on sale just about the end of the year. the updates are usually done September/ October. The cuurent one is 2011 the 2012 will come out this fall.
