I just bought the tt1 le at best buy for 139.00. I have been reading the threads on this site and others and I am getting more and more confused. Does anyone have reliable and complete specs for the le? Including chipset (sirf III or other), number of POI's in database, battery life expectancy, etc. Is the LE worth keeping or should I continue looking for a different GPS? Many users seem to have negative comments about the LE. Is it as reliable as the 2nd and 3rd additions. Sorry for all of the questions but a GPS is a luxury for me and I want one that is reliable and has an extensive POI database. I tried out a MIO C230 and loved it except for the POI's. Same with units from Maxx digital, Becker and Amcor. Any help would be appreciated.
