Want to swap my 03 NAVI head unit to an 05 NAVI unit for XM capability. I don't want the XM FM modulator kit honda sells. It takes away my extra space under the head unit for storage or I-VES DVD factory kit addition when I can afford it later. Would the 05 NAVI head plug and play into my current harness? if so, do i also need to replace the display panel above the center vents to display the new XM Radio graphics??? lemme know what to do...u guys are great...thanks!

 

Did you ever get this issue resolved? I changed my 03 coupe/navi with a 07 sedan with navi, everything worked except the display. Was a pain entering the radio code got it to work once now i forgot how i did it.
