I am wanting to add a satillite radio but still wan tto keep my stock radio. I havent seen any Sirius systems that I think would look good and the one from Mazda is only factory installed for 2005 ( which sucks )

Also had a queestion about rims. What do I need to do if anything to the rim to allow the air pressure sensor to work ?
or is this not affected?

 

Theres ample posts already covering both these questions. Use the search function and take apeek in the electronics forum and the apearance and wheel forums.
