Faulty Magellan GPSr Cables

Back in May I kept having troubles connecting to my GPSr which eventually got isolated to a fault in the serial cable. Someone else mentioned they had this same problem, so I thought I'd jot it down. Since its not a cheap cable to replace and only the common serial side was broken, I went down to Princess Auto to find a cheap replacement serial connector/cable. $1.40 later I've got the cable cut open and start mapping the pin out, it doesn't match the one I found online. Then map the new serial cable, solder the wires together and add some heat shrink tubing. My pin out for Magellan Merdian Gold serial cable:
