Garmin 702 shutting off

Recommended Posts

Hello All, just bought a 202 explorer that can with the Garmin 702 installed. I have had a couple of issues when hitting some waves the unit shuts down and takes about 20 minutes to recover and start getting satellites again to continue navigation. I seen a couple of post that the power cords are a issue has anyone had problems with the 702? Any recommendations for an alternative Nav chart plotter/fish finder?

I had a Lowrance with almost the same issue, but it cut off occasionally even with out any waves. Upgraded code a few times, but it still failed. I replaced it with a Raymarine A78 and have been very happy with its performance.
