This factory refurbished model 360 GPS worked for about ten hours. Initially it worked fine. It then failed to pick up the satellite signal or would loose the signal as a drove along on a trip. I called tech support for help twice. The service personnel are very difficult to understand and they also have trouble understanding me. It is a language issue. They suggested various tests and reprogramming but it did not correct the problem. The unit was fifteen days past the 90 day warrantee so they wanted me to ship back the unit and charge me $144.00 to examine it. I can't afford to pour any more money down that hole for ten hours of service. Stay away from the refurbished unit and don't buy a new unit without an extended warrantee.
