Question about Magellan RoadMate 300 GPS Receiver
I cannot get power once the unti is mounted and plug into the car power jack. Could it be anything other than a bad power adapter?
Recently I had a similar problem with my 300 - worked fine with AC power, but was intermittent with the power point in my truck sometimes it wouldn't power up at all in the truck).
I used a small nail file (steel wool would work too) to break the "glaze" on the outside of the small plug that plugs in to the unit on the power cord. It seems that it wasn't getting a good ground. Has been working great ever since - worth a try.
