Strolling thru a disappointing motorshow, I came across something of interest. A new company : www.allabout-i.com Piyapong Charoenkoopt MD.66 819859181 Young guy very enthusiastic. he has a map system which HE claims is as detailed as the ESRI maps. He is using Thailand Navigator 8. This goes on an SD card and can be used in as many GPS's as you like ...not tied to one. And te price is 6300baht. This card SUPPOSEDLY will fit most garmins...others i'm not sure. NOW I haven't tried the system but will be ordering one to use. This thread is for info only...no recommendation.
