Question about Magellan RoadMate 700 GPS Receiver
700 RoadMate keeps losing power. Cord has power light and I have tried it in several vehicles and it continues so I know it is not the power source of the car.
If it does what my Roadmate 9212T-LM do, it is not a power problem. On mine, partial power loss in the circuitry causes the problem to screen to blank in few seconds to few minutes. I can pull lighter plug out then in, picture comes back; instead of rebooting; which means computer stays up but losing graphic. I traced down to the uP6615A3 chip loses 3.3V on one leg but I can't find any info on the chip anywhere. the chip gets warm then, the leg loses 3.3V which causes screen to go black. it is worse( doesn't last) in the cold morning. anyone with uP6615A3 info will help me troubleshooting further.

I had the same problem. It was the pin inside the **** clamp that was broken. As I wiggled the plug in the unit the pin would dislodge. eventually the pin got lodged in the 12v power cord.
