Summary: /////Alpine Electronics is the industry leader in car audio and the flagship DVD based NVE-N872a Navigation unit is no exception! I prefer Alpine over any other car audio brand. I have this particular unit is all of my vehicles; they are very convenient, accurate, and a time saver. I feel confident that I will be guided correctly with pinpoint accuracy.
Summary: I've had several other Alpine navigation systems in the past, and had always wanted the NVE-N872. Well, that day finally came. The Pros: Install was about the same as the other units I've had. Alpine uses speed signals and an internal gyro, which helps, so if you are stuck in an area with poor sat reception, the system still knows where you are, and you can still navigate around. The display was nice coupled with the IVA-W505 that I had.
Summary: I bought this system to gain more up to date mapping and touch screen control. I always bought Alpine car stereo and Nav. products and I've never been disappointed. I like the interchange view to make sure your always in the right lane. While the building icons are neat they haven't been as helpful as I first thought, still not a bad feature though. Excellent GPS satellite reception even with the new small antenna/receiver. I only wish the update disc were cheaper.
