Metallic doesn't cause interference to the radio, it reduces the range of your central locking as the receiver module is in the cabin.
I've heard this too. The tint joints told me that it's not affected. I don't believe them on this one.
You won't have issues with metallic or carbon tint so long as it's good film and the installer knows what their doing. SunTek carbon film is excellent. I have a metalised film called solar guard by Quantum on mine. No complaints - visibility is good and no reception issues.
Yeah I've done a bit of reading on JC and I knew about your tint Tinny. I always rate your advice highly and that's why I was leaning towards metallic to begin with.
Diversity Antenna
The rear glass antenna system is comprised of the following: an antenna grid near the top of the rear glass which appears similar to the rear defroster grid, an antenna diversity module, and coax cables to connect the module to the radio. The radio supplies battery voltage to the antenna module via the coax cable. The antenna module amplifies the radio signals from the antenna and transmits them to the radio.
Never knew this, and neither did the tint shops. They all said "Nah the VE doesn't have an antenna in the rear window, you can have metallic all around if you want. Your mate with the FG will need a non-metallic rear window film"
Also, we ended up calling Tint-a-car in Essendon, just to see what two different franchises of the same business said. The guy there told us that Octane costs $295 (compared with Geelong Tint-a-car's $395 on sale down from $495) and Formula 1 costs $300, which we didn't get a quote from Geelong to compare with. I've got half a mind to make the trip to Essendon to get it done, still weighing up the options though.
