ok so i just bought the avic-d2. on the main harness there is an orange wire that says it goes to the "illumination switch". what wire would that be in the car and on what harness would it be found. thanks.

 

connector R2 (1st one for the radio), pin 10, green wire

 

oh thank you. also which wire would i splice the speed sensor to?

but ehh.. you can connect to that one yellow wire in the R9 connecter.. (the same one that has the radio controls and the aux wiring) pin 3.

but everyone's been using the plug right at the ecu... 2nd plug from top.. pin 17.. purple wire
(but it seems they relocated it to pin 8 on the '07)

 

dude squall thanks a bunch man. yeah those wiring guides were handy through the whole install. i just gotta finish it tommorow. too dark now. unless...

 

hmm.... you can always come by bamm's place sunday to finish.. i'll be there swapping leds.

he's in hayward.

 

ok so now i have different woes. all the wiring is fine. but the navi discs wont read and i keep getting the parking brake warning that its not hooked up properly and all that. everything else works great (normal cds, radio, video inputs)

 

you connect the parking brake right? it shouldn't be grounded when it's operating..

did you void the warranty... (like you're supposed to?) if you want it to operate in that manner?

 

um, well the stereo wire is connected to the e-brake switch wire. the handle itself seems to be the ground. im pretty sure its all hooked up right. i dont get it about voiding the warranty...

 

if you want the navi search functions and such (including video) to be usable while driving.. you need to flip a switch behind a sticker that will void the unit when you remove it.

 

ill check it out tommorow. but shouldnt there be a proper way to do it. i mean it should read the navi discs (while im parked mind you) and display the map regardless of whether or not the switch is grounded right?

 

oh yeah.. it should display the maps and everything

it's just you can't use certain features.. (like poi search and address book. and searching and stuff) unless the safety is bypassed.

 

oh ok. no but my problem is that the navi discs dont read at all therefore i cant get anything navigation related to work including maps.
