If you do a search, you will find plenty of threads up here discussing this, mine included.
You have stepped in to a world of pain my friend...:headbang: I completely understand the need and want for installing a factory NAV, but the amount of parts you need to get in order for it to work properly, and the time it takes are seriously not worth it when you can just go buy an after market, plug and play, that looks just about the same as factory for $400. Just my two cents, and I feel I know a thing or two about it since I did this exact install...but, if you still really want to go through with it you will need the following:
- JBL amp - this is what sends power to the speakers, there is NO power output from the head unit itself. Even if you have after market amps and speakers, you will need to run it through the JBL first.
- Overhead microphone - for phone and bluetooth and voice commands.
- Steering wheel bluetooth controls
- Nav unit GPS Antenna - Nav won't work unless it can find your car.
- Navigation Software Disk - Maps and info the NAV needs to function
- Wiring Harness including the different style connectors since they are not the same size as the factory radio
Once you assemble all the parts, get ready to do some serious amounts of splicing and reconnecting in your car, all of which is going to take a while to do it properly and troubleshoot if there are any problems. If you want a shop to do it, try finding one that will install it for less than $200. Don't think that is going to happen. Whatever you decide I hope it works out for ya. Good luck.:thumbsup:
