As has been on here a few times : Personalise a Garmin
Also, a bright coloured latex cover can help find it when it falls off…. Mine is red, so its fine for spring, summer and winter but in hindsight, autumn is a challenge….I lost my 1000 in the first month of ownership when it got knocked off the mount in the woods…
I was fortunate that I was using livetrack, so could see when it broke comms with the phone and backtrack to try to find it. After 30 mins search, a couple appeared and produced my Garmin from their pocket – they had been wandering around trying to find someone to give it back to!
After this, I did the following:
1. Printed some labels which stick onto the back of the Garmin under the rubber case – email, phone number etc.
2. Attached the elastic lanyard which I found in the box the same evening – this is now always wrapped around the bar and I have occasionally had it fall off and be dangling from it, so it works!
3. Added my name, email and contact number to the boot screen on the device as per the above link
4. Noted the serial number
In short, if I lose it again, the only reason it won’t get back to me is if the person who finds it doesn’t want to return it.
