Hey everyone...sorry if this has been answered somewhere already, but I can't find it...

I am going to retrofit my non-nav to nav; I am in the process of getting all the parts I need for the install and have a couple of questions for part numbers...

Parts:
Navigation - Found many of them on Ebay, but what is the p/n anyway???
GPS Antenna - 8610153530, 8686053050, both, or does aftermarket work???
Microphone - looks like there are 2 parts for this too, a harness and the mic., and will an aftermarket one work for this too???
Backup Camera - Part Number??? Can an aftermarket hook up to the pre-wired harness/plug???
Steering Controls - already have them.
Nav Harness - having it custom made now.

Thank you for any help you give, it will make my search much easier...and cheaper

 

Someone that has done the swap...can you help me out here...
