I bought this unit from a local commercial guy and never used it. A couple years ago, the day before I was taking my boat to the Keys, I was installing it with some buddies. The guy pulling the antenna cable was doing so holding onto the connector, the wire got stuck and it popped off. We tried to solder it but to no avail. A quick trip to WM just before close yielded me a Garmin and this unit has been collecting dust ever since.
I've turned it on and everything seems to be working just fine.
