Query: Website/Customer service is a joke.

I bought this product to use with my boat and car since it is advertised as being marine capable. What they don't tell you is that the marine maps do not come with the unit and must be purchased from their website. Here is the problem. I purchased a downloadable version of a marine map online which states it will only take minutes to download. Well, here it is 11 days later and still not able to download. I have been on the phone with their obviously overseas customer support staff over five times, and many hours with them trying to resolve this issue. To make a long story short, the website does not work when trying to download. If you do buy this product and wish to purchase a map, order the SD card version and have it shipped through the mail. Don't fall into the same trap I did.
