Query: Great GPS

No learning curve, figured it out right out of the box. Got me from Newport, RI to San DIego, Ca easily. The only problem I had was with the mount staying in position. It worked fine stuck to the windshield, once I got to CA and had to (illegal to drive with anything suction mounted to windshield) switch to the dash mount, any bump in the road would cause the unit to tilt down so that it was no longer easily readible. Fixed that with a bit of superglue, now it's fine.
