Summary: I recently received the Navigon 5100 as a gift (that I requested) and have been putting it through it's paces around Los Angeles. I am now returning it due to the fact that the routing is inaccurate and convoluted. For example: (1) to go to work the Navigon 5100 takes me three blocks out of my way only to have me circle back and go the correct direction. (2) When I stray off course the unit often has me turn around and follow the street it first suggested.

Summary: Rather than going into a prolonged review regarding the items I would like to focus on the issues that make this GPS most annoying. So much so that after having had it for 2 months I stopped using it altogether. Here goes, not in any particular order of annoyance: #1) Switching it on: there is a tiny leveled button that you, according to the manual, have to hold for 6 seconds to turn the GPS on.
Summary: I have found other, far less expensive, superior units than this one. The good: 1) Sensitive, accurate positioning. 2) Attractive design (if a bit bulky...) 3) Zagat ratings (when you can get to them) are fun and occasionally usesul. 4) Easy switch between 2d and 3d maps and easy switch from day to night modes. The Bad. 1) Long acquisition time from cold start (~5 minutes). From a stand-by start, it's <2minutes.
