If you go through Chiang Mai you could go see Eagle gps who might be able to help.

if you are in Bangkok, try ESRI -2-636-8421

EMBEE,
Having followed this thread, and others in here, for the opinions about Garmin rather than specific models, in your position I would get my 2720 back from my wife and convert her to using a smartphone with a downloaded app for in-car navigation

I know it is easier said than done; getting it back I mean.

This aspect has been bothering me also, a lot.
And, I have tried to get used to the Garmin approach of "I know best where you are going AND how to get there" but it simply doesn't know best!
Below is a cut and paste from a different thread of a post I have made on this - I am only shoving it in here because it is a big "no" factor for me about Garmins and I do wonder if they all act in this way.
Currently, I have been experimenting with OSM mapping on the Nuvi and it seems that the Garmin still behaves in this manner.

"Yea! Thanks for that observation Alex - I thought it was just me and how I have my Nuvi 205w set up; I have fiddled with the settings but it continues to do exactly as you describe. On one recent ride in France it appeared to want me to go back to Calais, even though by then I was miles and miles further south. This was quite perplexing at the time - I am used to a Tom Tom that does what I want (and constantly recalculates routes as I deviate, including when the French roads have their own, local, deviations for road works etc). In contrast, the Garmin gave me the impression of "I know best where you want to go (and make a U turn now!!)".
Two other features of the Garmin that I did not like were (this is my first trip using one of these);
It seemed slow to do the calculations compared with my Tom Tom.
Over long route calculations it more or less "gave up" and came up with a message that more information would be provided later. In contrast, the ancient Tom Tom can come up with a route across most of Europe."

Walkabout, yep that was always a problem with me too.

I was on the opposite side of Oz and my TTR2 told me I had 7500km to get home, it had no issues with this at all. I tried to navigate from Frankfurt to Istanbul with the Montana, the route was truncated by the Garmin. What was worse, it decided to forget the bits it left out so I had to redo the route when it came to the end which was the middle of nowhere, very unprofessional imho, it should be able to do a direct route down the Autobahn.

The other thing I hate was the fact it did not use my current location to chosse which destination was the most apt. EG: I was on the west coast of Ireland and decided I wanted to go to Belfast, which was about 350km away. The FIRST choice on the list of towns was Dublin, Christchurch, NZ, 15,000km away, the SECOND was in South Africa, now what sort of frickin idiot designs software like that, brain dead morons that is who!!!

Anyway, rant over

Cheers
TS

Thanks for the tips Bertrand and the phone conversation certainly helped.

The end result is, I called ESRI who said they cannot repair the Montana under warranty and nor can Garmin Taiwan, it has to go back to the USA or Europe

That sucks, just waiting for the time zones to catch up and make a phone call to Southampton I guess, I wonder which is closer, the US or England, it will cost a bit for postage though

I will try that number I have and see what transpires, or I may just wait until I get back to Oz.

Cheers

really? Djeeez what a biz- it's a small planet indeed when there are only 2 places you can get a garmin fixed -

Yeah, too true, but I came up with a good result

I told them at Garmin Europe the screen was broke after many freezes and failures prior to that. They said the screen was not covered under warranty I told them the only reason the screen is buggered is because I had to keep pushing that part of the screen doing a master reset in that exact spot at least twice a day for months.

After that was passed on to the tech, Mark, I got a result, send it back, we will repair under warranty

Great, so now I need to send it away and they will turn it around within 5 days, so I MAY get it before xmas

Cheers

Nice Xmas treat from the lads at Garmin-

Better than that, I have it here right now

I had to go to Chiang Rai to pick up a spare part for my bike, while there I was called by the receiver of the Garmin in Chiang Mai and he sent it up overnight by bus, so a bloody good turn around by Garmin

The service is good, so now lets see if 3rd time lucky will get me back home. I still have another 3 months, so numerically, the odds are against it still being a useful item by late January

Cheers from Luang Namtha, Laos

I agree with what Richard has to say the speed of the Montana when it has a lot of streets to navigate (ie middle of London).

The highest model Zumo is a pretty good unit with the latest firmware, doesn't have all the features of the Montana.
