Bill,
I had the same problem after owning and running for 2.5 years (went out this past fall). So of course, happened a few months after my warranty was up. But I ended up taking mine to Motor Clinic in Bloomington, MN (recommended by Rapid Marine and Cabelas). I took it in after I went through my batteries, re-setting/unhooking/rebooting everything, etc…..everything in the manual and what a guy familiar with motorguide told me to do. The down-side, had to take my trolling motor off my Ranger for them to even look at it.
I did call MotorGuide customer service and they were good and said that they will look into my situation once we know for sure what the issue is….assuming GPS module. Told them the truth, I’ve always been a Minnkota guy but tried MotorGuide because of the 5′ Jog feature while on anchor mode and the connectivity with Lowrance units.
One thing I did notice when I dropped off my MotorGuide, is how many trolling motors they had there to work on….both MG and Minnkota.
So yes, a pain in the @ss and still don’t know what the damage to the wallet will be, along with what MotorGuide may do for me. But will all be my deciding factor on what trolling motor I use in the future.
