Hi everyone. I have something which is puzzling me. I have tried connecting my Garmin Zumo XT satnav to the auxiliary plug on the left side of the bike so it powers on when ignition is switched on. However, all it does is turn on but does not charge. The power from the plug is 12v and at the satnav mount 5.14v which is all correct. So why does it not charge? I have had to wire it straight to the battery which charges it fine but a hassle trying to remember to switch it off. It's a brand new Garmin, in fact it's a replacement as I sent the original back for the problem mentioned. I tried it in the fog light plug (using it for fog lights) and it shows its charging when switched on so I know the device works ok. Has anyone any suggestions as to why the satnav doesn't charge when plugged into the auxiliary plug? Am I missing something?
