While on a trip, the power/traffic receiver cable for my 540XXL failed--the center pin of the cigarette lighter plug was gone, nowhere to be found.
I purchased a replacement power-only cable from a Radio Shack because I REALLY needed the GPS to get around. But there are two deficiencies...
a. It is power only--no traffic receiver
b. The right angle plug on the cord at the device is much too large and extends below the envelope of the display.
what I would like to do is cut off the cigarette power supply off the new cable and put it on the original cable, but I need to know the wiring connections.
First, is this possible? I am assuming there are only positive and negative 5v wires coming out. Are there more than that? And how do I tell which to solder to get polarity right?
Thanks
