hi all.

i am planning to get he V-kool highest grade for my new car.
couldn't stand the utter heat from my previous experiences.

my question is;
this time i kinda had the installed a gps in the car from the car manufacturer itself.
would it be affected also since it not a gps from smartphones?

i am also worried if the smart tag that i am using now will be affected.

is there anyone here that is using the v-kool highest grade tinting and experiencing such problems?
please share if possible.

thanks.
