I just received my Garmin Zumo 350 from PalmDr. Also called Short Tronics, INC. They fixed my Zumo 350 for about $70. Quick turn around and great communication. https://www.palmdr.com A few week backs while moving over my Zumo 350 cradle and battery adapter from one bike to another, I noticed the unit would not boot in cradle with ignition switch. I tested it with another cradle and power adapter. So, I decided to take chance and ship it to PalmDr. They diagnosed the problem in one day. My power module chip was bad. All back up and running.
