I'm no Garmin tout. In fact my first Garmin was a Street Pilot 2610. At that time, it was a VERY expensive unit. I loved that GPS. Garmin in their wisdom changed the map format and the new maps were not compatible with my 2610. I emailed them asking when I could expect a software update. I was informed that they had no plans to offer any 2610 update and I was advised to buy a new unit. I replied that I would not be buying any new Garmin.

I looked at every other brand available and none offered a decent Thailand map. If I remember correctly, ESRI had the best map and it cost a bundle. I don't remember for sure but it was either 13,000 or 17,000 baht. It would only work on Garmin units. ESRI dropped the price to 7,000 baht and I bought a new Garmin and the ERSI map. I thought that Garmin was very sneaky by changing the map format.

As a side note, a friend of mine is still using the old 2610 with the very outdated map. It suits him and he is happy with it.

Google maps for smartphone (I use HTC Desire). Works well in Bangkok BUT you need mobile phone signal.

I have Android 2.3.4 and Google gives me the message that navigation is not available in my area. It will show me where I am at and give directions but no navigation. I also find the map is quite cumbersome to use. Nothing simple about it.
