I got one for my truck, I THINK it's model: Dual XHD7714.
I've owned mine over 6 months now, run it hard, have had everything connected to it and it works well.
After I got my Evo, I started exclusively using the Bluetooth connectivity for Pandora and local media I had copied to the SD card. Never had any issues. Phone calls come through clear as well. You can even control the basic play functions from the head unit as well (to your phone).... such as skip songs in Pandora, pausing, etc.
I have it hooked up to multiple amps (full speakers, subs, etc)
No issues at all.
My Evo and the radio connect very quickly every time I get in the truck.
Not bad for $100.
