I'm looking to buy the AutoChart Pro software but the only thing I can find is a DVD version. My new Laptop, as well as most of the newer desktops and laptops, no longer have DVD or BluRay drives so can the product be downloaded from Humminbird if you buy the DVD version? I know you can buy a downloadable version off of the Humminbird ChartSelect site but that is at full price while there are plenty of legitimate sites which sell the DVD version at a significantly reduced price.
