My battery died, I replaced it and have the codes, but have no power to the Nav system. Don't see a fuse for it in the layouts I have found on line. Can anyone help? Thanks

 

There are two fuses that supply power to the Nav module; No. 32 (7.5A) and No 7 (10A) in the under dash fuse/relay box.

If these are good, there is a "forced start" of the display. This requires installing a shorting jumper on the service check connector (SCS) in the harness at the backside of the navigation unit. Turn keyswitch to On and system should dispaly change to the "Navi Systems Link" screen. Remove the SCS jumper.

good luck
