Just read the whole thing - nothing.
So frustrating. How can such an expensive bit of kit be so useless?
I can't help with your specific problem but if its any consolation you're not the only one to have difficulties. The 800 I had was useless, incapable of remembering my country let alone location, used to re-route me on to the nearest motorway and several other stupid issues.
After 10 days of frustration I took it back to
Evans and got a full refund. I was very disappointed at the time. I'd spent weeks agonising over my decision to spend so much money on this. For me it was really a vanity, bit of fun, purchase as it doesn't impact one's riding ability. Something I wanted but didn't need at all but eventually justified to myself!!
As I recall the tech support was non-existent and the website pretty flakey and constantly threw me out. Overall a very poor experience.
I fully appreciate many, many users have a great experience with Garmin. Mine is the opposite, such an expensive item should work out of the box after charging and basic set up.
I'd never buy a product from Garmin.
