I am considering investing in a GPS/Sat-nav system to mount onto my Tenere, but there are so many on the market, and there seems like such wise people on this forum, I though I would ask
        
 
         
        
         - what GPS system do you have, or recommend?
- how and where have you mounted it?
- how have you powered it?
I know there's usually a trade off between cost and quality, but i'm looking for a cheaper unit that can accomodate UK and Euro maps.
         
        
 You collective sage-like advice and suggestions would be welcome 
        
 
         
         (Apologies if I have duplicated a previous thread, I have had a brief look and didn't see a recent GPS/Sat-nav thread)
