Let me introduce my vehicle first.
Year 2007
model Tl with navigation and XM radio

i had best buy install Pa15 Acu Xl on the vehicle, but the navigation system froze after the installation and only the backup camera will work. I think the product is compatible with my car and the installation should be correct.
Has anyone ever experienced this kind of problem before? Do you have a solution for it?

thx in advance

They might have been dumb and plugged the unit into the back of the navi drive rather than into the back of the XM receiver or the back of the head unit. Call up best buy and ask them where exactly was the unit plugged into.

I actually see that they plugged the unit in the XM receiver in the trunk

that sounds odd, i know it can freeze up the system but as far as making it non-functional, that's new.... Have them take out the unit and update it, it might be running on older software...
