I have a 2008 grand touring with factory 6 disc changer 5.1 Bose Centerpoint. I would like to upgrade to factory navigation. Can it be done? Is the wiring harness in place?
Don't do it.. It's not worth it.. Just get a aftermarket.. I have a GT with Nav... It's ok, but I miss my Acura/Honda nav... You can use it while driving... Mazda you can't
