Bests & Worsts Reviews from Amazon

I've used GPS based automotive navigation systems in Mercedes Benz and Acuras and have found them to be less than satisfactory but the Garmin 2620 is an awesome bit of kit. The unit is easy to use and with the beanbag base stays on my dashboard unless I'm doing something really stupid (high speed U-turns). With the external antenna I almost never lose the satellites, and the unit quickly acquires and reacquires the satellites as necessary. Navigation is excellent, I disagree with some of the Garmin's routing choices but only on routes that I know well and have driven on extensively. The system remote is easy to use one handed and if you disable the annoying safety feature that prevents you from programming on the move you can easily set destinations or change route settings by touch and by glancing at the screen. The screen is bright and clear in sunlight and the unit does not seem to have been bothered by sitting on my dashboard in the hot sun or by occasionally being knocked off the dash when I do something stupid (the aforementioned high speed turns). As far as the reviewer who says that he's leaving out bait for thieves by having this unit on his dash I'd recommend the optional carrying case, it's a matter of a few seconds to disconnect the unit from the power cord and external antenna, put it in the case and stow the case under the seat or somewhere else out of sight. If I were purchasing a new car I would save my money and get a Garmin 2620 instead of purchasing a built in navigation system. Most built in systems cost more money and while some can give you better accuracy with dead reckoning sensors that read vehicle speed and direction the extra money you'll spend for the additional accuracy is offset by being locked into a proprietary solution.
