I purchased it from Hoges Marine in Tampa, best price I could find online. I got it running ok but the thing wont hold a course, it starts to then goes hard to port and stays there. I may have to call Garmin tech support while on the water. I got the calibration done riding in circles and got North set as well. I have it hooked to my HDS12 I tried setting a route and use the gps track feature, it starts ok then starts wondering in a circle. I am at a loss.
