Multipurpose head unit, size of stock JBL stereo?
 

I don't even know if such a thing exists, but ideally we're looking for something with the following qualities:

1. Same size as the stock JBL head unit
2. Stereo w/ iPod connection
3. GPS
4. Back-up camera

Any info would be great.

Cheers,

John.

Usually can be had on eBay for around $750 with the Bluetooth and iPod add-ons. Unless you're quite competent with wiring, I would consider having a shop do the install for you, since you have the JBL system and they're not as straightforward as a regular system.
