I own an 05 TL w. Nav and the other day I had XM update my service to the Nav Traffic for a free trial! The sad part of it all is that I can't get it to work. I called XM 4 or 5 times now and they supposidly updated my XM, but I still haven't noticed anything different with my Nav. Does anyone know if it's a common problem or is it because I own an 05 TL and it's not compatible or updated to work with the older unit? Makes no sense.. Some help would be appreciated.

Thanks

 

05 TL Nav is not compatible with the XM live traffic. You need the 07 Nav system. My my understanding its pretty expensive to with the hardware to the 07 Nav.

 

The '04-'06 TL uses the 3.X navi system which does not support XM Nav Traffic. Beginning with the '07 TL, the navi system is version 4.X and supports XM Nav Traffic.

There are some links to threads discussing the swap in the 3G TL Audio & Electronics FAQ.
