I do have aftermarket NAV but its been installed since 07. this problem came up when the 295's were installed. They told me today they were replacing the PCM....There goes my PCM4less tune. (kelly said they would redo it! Thanks Kelly) I didn't think the PCM had anything to do with tire pressure. The dealer has me in a 08 H2 as a loaner. Might trade it in!

 

I just ordered my new wheels and dont plan on putting in tire pressure sensors, Ill deal with the stupid light on
