The power cord that came with my 930 went bad. I have tried to use a standard USB cable with a USB cigaret lighter plug adapter. This setup appears to charge the battery (if the unit is off) but can't keep the 930 on continuously. I keep getting a message that the battery is low and the unit shuts off. I have tried several cable/adapter combinations with no luck. I hate to buy the expensive TomTom power cable only to find that the 930 is the real problem. Has anyone experienced a similar problem?
Thanks.
Thanks.
