Recently picked this up to replace a dated, although fully functional Garmin GPS-V and WOW what a difference! The satellite acquisition is super fast and at least a full minute quicker than the GPS V. Route calculations, re-calculations and map redraw speeds are simply mind boggling in comaprison to the GPS V. I also like the fact that you can update the unit's already HUGE 700MB memory bucket with inexpensive SD cards.Accuracy: No GPS is perfect and I have had some "interesting" route suggestions by this(Same map data as the GPS V), but none have been dead on wrong. 99% of the time you can count on this device to get you where you need to be. This is more than I can say for the TOMTOM Go we use at work, which you consider yourself lucky if it can find itself out of your driveway.The voice prompts are clear and concise. You can even add various accents. I currently have mine set to the Australian female. (There are only female voices, by the way). The unit alerts you in plenty of time for you next turn, exit, etc. The unit also has a few other bells and whistles that I find more of a niche than neccessity, but all work well. Compared to my iPod Video 60GB, the MP3 audio is 95% as clean and the controls are very intuative. The photo viewer is a nice touch as well.All in all this is honestly THE best GPS out right now for mobile navigation. You can even get a traffic update box from Garmin that monitors RDS traffic data and reroutes accordingly for slow or non-moving traffic. All the functions and features work to a T. Highly Reccomended!
