Will an external GPS antenna kept inside the car improve reception?
My car has a v-kool athermic heat blocker (v-70) installed on the front windshield. When I installed my Mio P350 GPS device I found that it’s not able to lock on to any satellites.
Will an external GPS antenna kept INSIDE the car help in locking on to satellites. Or will it have to be placed outside the car?


I have an antenna for my own mio, and although it did work inside the car, the connection was easily interrupted (nothing that i can specifically pin it down to) but once i placed it outside it worked perfectly. It’s magnetic and waterproof.
This is similar to the one I got but it’s cheaper!
