Bought a used garmin 327. I need to desolder and solder a new antenna cable on it. Any tips or ideas on getting the old coax off? There is a massive glob of solder on the BNC connector. I am concerned about melting all the plastic? I was thinking a pencil torch because I am not sure a regular soldering iron would get hot enough to heat the mass of this. Or will a regular soldering iron work? Any ideas/thoughts would be appreciated.
