Summary: I bought this Garmin product because I owned a 'refurbised' one just like it (til it was stolen)and it performed 'flawlessly'. However, I'll never buy another 'used' electronic item again. This GPS product starts out working good until it gets hot, then it jumps around through the screens and 'skips' the screen I need. I performed a 'Hard Reset' (to factory defaults), but did not help.
Summary: I cannot agree more with Ivan Osipkov's review. Here are his review plus my comments: A few things that may not be immediately noticeable until one actually buys the device: 1) the device does not have internal battery, i.e. it needs to be continuously plugged in; This is very annoying. After you programmed your route, you started engine and your program got lost due to lost of power. Basically you have to reprogram it AFTER you started engine!
Summary: On the positive side the unit works fairly well for navigation in most situations and on occasion has proved to be a big help in routing around traffic jams. On the negative side, the FM transmitter is terrible. There is an audio output if your car has a direct audio input line in. I do not use the XM feature anymore due to the sound quality and less than adequate reception when in the vicinity of trees.
