Summary: I had this GPS for a little over a year. It worked absolutely perfect and was used on literally a daily basis over that year. However, after the 1 year warrenty was up (as if on cue) it suddenly just "died!" It was not dropped, scratched, exposed to weather elements or anything!!! It just simply went blank and quit working.
Summary: I got my 5310 from Costco without checking the online reviews. Since I am a Amazon customer and know their review system are fair, so after I used 5310 three times I'd like to post the review for this product. I am a regular user and don't need the 05/2009 map (so far) and the other common functions are good. But I notice that the battery doesn't hold for 3 hours as the manufacturer said. It ONLY GIVES LESS THAN 50 MINUTES battery usage after two-day charge.
Summary: I have shipped this one back and received a new one. The first one I received looked used not new. However, the performance of this unit is not great. I liked the roadmate 800 better. The 800 was faster all the way around. The maestro takes too long to re-route and way too long to search for a point of interest, sometimes as much as 1 minute to locate a POI. The POI editor is too complicated ot figure out and I could not get it to work.
