How would I find out? I looked in the compartment in the back and didnt see any boxes back there. Where would I look?

Find the TCU and verify the part number. Here is a post with a listing of TCU part numbers and whether they have Bluetooth.
Here's a great TCU part number reference

The TCU is located in the rear compartment, by the CD changer and DSP amp. If you have navigation, I believe it sits above the navigation bracket.

Thanks for the info. Judging by the link I wouldnt have it. I'll check the back tomorrow to find the tcu. I dont have nav, but I would guess its still in the same place.


Where would I find a newer one If I wanted to upgrade to a voice and BT one? New or used?

I would search something like eBay for a while for a newer module. You can get them for 50% of the new price.
