Bought this unit new for a planned extended boat trip up the coast from VA to LI SOund. After three software upgrades (all installed because the unit was freezing up) made the unit completely inoperable, I was told by Standard Horizon customer service to return it to CA AT MY EXPENSE and they would ship a replacement unit to me. Upgraded software chips had been mailed to me all along my route from VA and each one lead to only more issues with the unit. Very disappointing!!!
