I am having problems with my Garmin Tourer Plus One. I use it in our Land Rover Freelander 2 which has a heated front windscreen.
The problem we have is can take upto 10 - 15 miles or twenty minutes to log onto a Satellite which is not acceptable.
I have read that front windscreen heaters can effect or block the gps signal. Once it logs on it is fine, so:
1. can I fit an external GPS aerial to this model
2. Will it make any difference
