I have a 2008 Mazda 3 GT with a basic stereo that has an SAT button that apparently is useless. Have spoke to my local Mazda dealer and even attempted to have a sirirus satellite module installed but it did not work. The module is only good for a 2008.5 and up which they found out after the fact. Anyhow, don't want an aftermarket as I do like having such a simple feature as my temp control. Would like to have a satellite funtion in my head unit and if there are other features too great. Does anyone know if a 2009 Mazda 3 (Luxury Package) head unit will fit into and actually function 100% in my 2008 Mazda 3? Any other suggestions would be helpful.
