    My first one had this issue after two rides......Garmin were good and replaced it under warranty.
    Second one did it after 4 rides but they didn't replace it charged me AUS$290,00 as it was out of warranty as I hadn't been riding much during that year,.

    Appreciate the advice on the fix ,if ive got to fill it with chewing gum or whatever it takes I will...! Hate losing good track because it fails, or getting lost because it fails......

    Mine is mounted on a rugged mount on top of the handelbars on a ram mount. I don't go slow on the bumps though.....
    cheers

    Bring a cheap external gps antenna you can plug into the Montana, in case it fails as Hodakaguy's did. When my wife's Montana had the problem, we used it for a few weeks with the puck attached and it seemed more accurate than normal because of it.

    This kind of thing can be found for as little as $25.

    I wonder if Garmin did something to fix this in later models. I guess I didn't see this when it first came out. My Montana has been thru some bad crashes with no problems. I ride with a lot of guys with Montanas, and nobody has had the problem. I used to carry the aux antenna with my GPS III+ because it was easy to break the antenna off that bike.

    But maybe I will look into the aux antenna for long trips.

    Despite rough and frequent use mine is still working great. I used clear silicone and was careful not to be messy and judicious.
    The outside is getting to look a little "loved", but the only problem I have is the occasional white screening when turning it on.

    I forgot. Mine was doing great until it fell out of my truck and I apparently drove over it about a month ago. There was no external damage, but the screen was trashed. I traded it in on a reburbed unit.

    Hot glue can create a parassite capacity that can shift the resonance frequency of the quartz.
    It is not recommended to use hot glue on electronic components.

    Do not use hot glue, use silicon specific for electronics !

    Just seen this and wondering if the loose antenna could be the reason why my new to me 600 unit won't pick up any satellites whilst under cover, where my cheap Dakota 10 recieves good signal everywhere??
    Any learned opinions please.

    Does it rattle when you shake it? Should not hear anything loose inside if the chip is secure.

    And if you have an external gps puck you can plug in to see if it works better.

    But when my wife's 650 broke, it didn't pick up any satellites at all, cover or no cover.

    No rattles and i don't have an external aerial but i think i should get one. Just very irritating as here in the hills there is plenty of forest cover. I also use the gps to plot potential power line routes through the forests. Dakota works well, Montana very iffy.

    Well there might be something wrong with it. Have you tried a factory reset?

    If it is damaged, you can always get a refurbished unit through Garmin's Out of Warranty program.

    It's going to cost you around $170, but it's better than putting up with substandard performance.

    A Montana should work at least as well as a Dakota.

    Did I mention I am in Tanzania, warranty's mean diddly-squat and posting stuff is expensive. I'll try the reset and work from there. Had an old 276 that was great and now hear there is a replacement, but 600 plus euros . Thanks for the advice, I'm sure I'll fix it somehow.

    Go to your Satellite screen on the Montana and see what is going on with getting satellite connections.

    This should give you a pretty good idea of what the problem may be. Seeing as you are close to the equator, your Montana should have lots of satellites to choose from.
