Guys, I am confused after watching youtube My Android HU came with a GPS antenna and was looking at the best possible placement for it. On YT, some recommended: 1. On the roof of car next to the Radio antenna 2. On dashboard in front of the windshield 3. Tuck inside the HU compartment by sticking it to any metal surface inside Those with aftermarket GPS antenna, where do you place it to get the strongest possible signal My GPS antenna support both Glonass and GPS
