Montana 700 series crashing and freezing.

Dear Sir/Madam.....I am onto my third Montana; I returned the first unit (700i) under warranty as it kept crashing whether it was in the car cradle or in my hand. That means that when Garmin advised of a fix that meant modifying the dampeners in the cradle, my first thought was they were barking up the wrong tree, so to speak and so it was. My second unit was also a 700i, it became apparent soon after delivery that the problem was in all units because this until behaved the same as the last one. I am not a computer guru or specialist but I am an air traffic controller and ships navigator by trade and have been using Garmin since it's conception, so as an end user who knows how to put these units through their paces, it is not difficult to come to the conclusion that the processors or cache in these units cannot handle the load. That being my suspicion, I asked for a refund on my second 700i and bought a 700 thinking that since the unit had less 'unnecessary' junk in it's programming, it might be able to handle the load. BUT, even with bluetooth turned off as well as topomap, the unit freezes up and shuts down. To confirm my suspicion on the incapability of the units processing power, I tried what I have been able to do on just about every model I have previously owned, and that is, to zoom out on the map page to the point where the whole of Australia would show on the screen and see how much info the unit is able to process. Eureka, never got anywhere near showing Eastern Australia, no matter how many times I tried....IT DOES NOT HAVE THE PROCESSING POWER. Garmin, I don't know whether this time you have tried to cut costs by going 'el cheapo' on a component or it has been a tragic mistake by your engineering side, it does not matter, but you must look at the issue mentioned here and do what you can to pacify your client base before they turn elsewhere. You have a great reputation, always have had and we realise that mistakes are made regardless of who!

Sincerely.
