I recently purchased the GPS antenna from Fasttech (1020200) for my 2015 Nissan Leaf SV. How have others been mounting the antenna? I was considering mounting it to the rear window originally, but I'm now concerned about interference from the rear defroster. Perhaps flat on the dash would be better, but it would also be nice if there were a way to mount it on the underside of the dash.
Ended up installing the antenna on the front windshield on the passenger side (North American car); seems to work great!
