I purchased a garmin driveassit 51 lmt-d to upgrade my previous garmin GPS. (had it six years) I wanted a HD camera. Do not have the Camera operational while trying to Navigate round. It does not keep the routing upto date. We contacted Garmin support. They said put a High Speed SD card in the device. (it already had one). So I tried two other makes and also the card they sent me oh! free of charge (4gb only) they all showed the same fault. Garmin still do not accept the device is at error. So now DO NOT GET ONE. I have being using Garmin GPS systems since 1995 so am very disappointed.
