If the battery in your gps is toast duct tape two 6 volt lantern batteries together. Solder a wire between the positive and negative just like putting truck batteries in series for 24 volts. Attach a cheep cigar lighter to the batteries and you have instant 12v gps power for your recovery trip. I put one of these together about a year ago and it is still working in my 24 volt vehicles.
