But I want to find out if there is an aftermarket nav system that will have:

Backup Camera
XM
Bluetooth with the OEM steering wheel controls to work the dial by voice, answer call/disconnect call.

I work for a Toyota dealer, and I think my aftermarket A/V installer is about as retarded as they come.

Thanks!

I think the new Eclipse AVN726E has all that. I don't think it has been released yet though. The Eclipse units have always been plug & Play with the Toyota oem steering wheel controls and the 726E is the first Eclipse unit with built-in bluetooth.

anyone know for certain which units work with the oem bluetooth buttons on the steering wheel?

I can tell you that the pioneer avic F series don't work with the factory blue tooth buttons on the steering wheel. However, the other steering wheel functions for the audio do work. On my Avic 7010BT, the blue tooth is activated via voice or by selecting it from the menu of the units display. I believe pioneer uses microsoft sync for audio commands like you see in the commercials.
