I just bought this car and I'm still in the process of customizing it and the next step if window tinting, and I wanted mirror tint but the guy who is doing the tinting said it would screw up the Navi system on because it has metal in it. It doesn't sound too far fetched, but it got me thinking can I put tint on the car at all with out having a problem not mirror tint but just regular tint sense the mirror tint is out now.
