Query: Great Navigator

Does everything it is suppose to, the navigation is clear and accurate. Once I spent the time to download the updates, all 2Gb of them the unit performed even better. The two downs I have encountered are, one the volume from the internal speaker is low if you like to drive with a window down or passengers are continually talking. This can be overcome by chaneling the audio through your cars stereo or a blue tooth head set. Second down is if you want to use the life like freeway exit screens or lane assist then you are stuck with one of the computer voices, as soon as you change the voice to a human voice the lane assist is off. This sucks because the lane assist was one of the reasons I chose this model, on my old tomtom I like using Yoda as the voice and I have gotten use to hearing him.
