GPS Connection
I have LX 570 S 2015. I installed the V-Kool firm on the glasses to reduce the power of sun inside the vehicle. Now, I cannot receive GPS signals and the map always shows wrong position. I don't want to remove the firm, because the sun here is too much hot and also I've purchased it expensive.
I've spoken to Lexus Dealer, but unfortunately they told I should remove the firm to receive the GPS signals.
Can I change the antenna to one stronger one?
Or,
Can I install the new antenna like Garmin outside of the vehicle?
