Not a problem, glad to help. The lake maps for the Nuvi would run $116 and change for preloaded cards per region, OR, get the DVD with maps for the entire US for $129.99. Just search "inland lakes" on garmin.com or look for it on the Bass Pro site. And yes, Lowrance's customer service IS HORRIBLE for both crossover units AND fishfinders (believe me, you have no idea the amount of complaints I hear).
