I recently went to get a quote on all around window tinting and was told I would need special tint on the rear window for two reasons:
1. Radio reception would go down. (don't care, got sirius)
2. The metalized film tint would also block out signals to the GPS receiver located on the rear deck.
I was told I needed to either get ceramic tint (which doesn't come in limo

) or get the dyed tint (the cheap stuff that turns purple).
Does anyone have a factory GPS with their windows tinted with metalized tint?
Or has anyone tried and found out they lost GPS reception?
This guy wouldn't lie to me to pitch me a higher priced product. Plus it's only about $65 difference in price.
True or myth?
