a Garmin nüvi 42 purchased in Bangkok this year. I have the initial map version 2013.10, which I try desperately to update to 2013.30 (DUAL). I am connected and registered to www.garmin.co.th, I have the updated communicator plugin n (Version 4.1.0.0) installed. BUT I still cannot download the Garmin City Navigator Thailand 2013.30. I need DUAL version (Thai/English). I tried to call customer service, no answer. Why is that so difficult to update the map!?!?! Please provide an answer and solution. Tks.
