I have a Nuvi 200 Garmin.....and I called Garmin and they told me no. I was actually going to get another GPS. The guy I spoke with at Garmin told me since I would be using in both offshore and inland lakes that I should get the Oregon Series 400c (this one has the costal maps already downloaded) which is 500 dollars and then I would have to download or order a card for it to get my inland lakes. If I just wanted the inland lakes then I could just order the Oregon Series 400i. I think it was the same price...but call them and check. Hope this helps ----Tight Lines
