Got Tint?

Got the ride tinted (for about 3 bones inc. tip) with 18% Llumar Axcess. This stuff is supposed to be the best tint out there right now. New carbon-based non-metallic tint is supposed to be the enemy of UV (98% block), but RF-friendly so as not to interfere with bluetooth, AM/FM antenna, etc. Once it was installed I put the GPS in the hatch window and it synched up easily with 6 SATs. The signal strength indicator did not change visibly when I moved it in and out of the car. The FM and AM signals are fine. No Tire Pressure Monitor or Keyless entry issues. Either I bought in on hype, or this stuff is for real. Regular tint would have cost about 1/2 the price of this. Gah!
