The first thing I would do is test for power at the cradle mounted on the bike but I would use a test light not a multi meter.I have the Garmin 350LM and have it mounted to my Wee on a RAM mount on the Richland Rick mount under the windscreen. I have the unit powered/hardwired to my battery. During the first month or so that I owned the device it would charge while mounted on my bike. But now it has mysteriously stopped charging while mounted. It charges when I plug it into my computer when off the bike. But of course this does not help me when I am riding and wish to have the unit direct me for longer than the 2 or 3 hours of battery life! I have checked fuses (all ok), contact points are clean, wiring appears ok, battery connections are good. But I cannot find anything that seems to be responsible for the recent lack of charging capability. Could it be the 350LM unit itself? Any ideas?? Suggestions?? The GPS unit is over a year old now so no hope of any warranty support. Honestly, I think I have used the unit a total of about 8 hours while mounted on my bike without any problems until it just mysteriously stopped charging.
