I haven't tried that on mine, but I doubt the GPS18PC or the scanners USB jack is physically wired that way. I do know that the cigarette lighter plug is also neccessary because it drops the voltage down from 12 volts DC to 5v.pointy said:I know that the above GPS works with the 996 radio. What I want to know is can you get a serial to USB adaptor so that the GPS gets its power from the radio instead of the cigarette lighter adaptor supplied with the GPS?
Thanks You.
