Reading about all these "peculiarities" with Garmin and mapsourse makes me glad I sold mine. I could never get on with it and felt the software rather poor and obstructive to use. I now use a Becker sat nav which has found everything I have asked for in seconds. It is sooo much better than Garmin.[/QUOT
Which cartography does the Becker use and how much are the updates? Just had a look at some but didn't find a waterproof one so I guess that makes them pretty useless for bikes in the semi aquatic UK. Do they come with mapping software?
If I remember correctly their radios used to be fitted to Mercs and were very good.
