Disk changer
 

Ok I have a 05 and it only has the normal cd player. I would like to put the factory disk changer in my car. Can it be done or is there other things different between the 2. I know it will cost alot so if you have any other ideas let me know.

All depends on the firmware of your existing headunit. 9.55 or better, with a couple exceptions in the middle and it should be plug and play lol. I love plug and play in this car heh.

Actually, looks like firmware may not even be an issue. If you do some digging you can probably find it a little cheaper.
