I installed a nav unit from a 2006 STS in a 2008. Everthing is working corrently but the steering wheel controls for track and seek do not work. Volume up and down, mute and source all work. From looking at the wiring diagram it looks like there is a diffeance in resistance in the 06 and 08. Just wondering if anyone else has ran into this. thanks

06 only had the seek-up/down they could not check presets up or down (unless you deleted the heated wheel you got a 1-6 button and in 07 you lost seek down for a 1-6 preset button but anyways...), probably a software difference, try taking it to the dealer complaining of nav issues, they will run a software update on it, which hopefully will calibrate it for your cars systems.

Yea, either way go to the dealer and tell them that the NAV is acting up and you would like a firmware update. Depending on the dealer they may or may not know what you are talking about.
There are a few threads on here about the FW update. You can get the TSB off of one of those threads and bring it to the dealer if they give you problems.
