Right now I have the BrandMotion Magellan 760 on top of the dash. Map updates are hard to get for this unit so I want to replace it with something in the DD dash area. I would like to keep the 5 CD player capability, but replacing that with iPod or other devices would not be an issue. I would also like to keep the steering wheel controls for music functions. Blue tooth phone paring would be nice. But most importantly I would like it to have great GPS capability and vendor support for future updates, that Magellan does not provide. Also, really need a backup camera support.

What are my options?

What should I stay away from?
