$245 is a ridiculous price! That's $245 profit for BMW. You could buy 2 new Garmins and get more features and greater ease of use. Garmin gives you the actual Posted Speed Limit for the road you are traveling. My last car I paid $2300 for the GPS and it didn't have PSL. This is such an important feature I don't understand why it isn't offered on far mor expensive GPS units.
Sorry about the rant. I miss my Garmin.
