Navigon uses several ways to refer to this program, so here is a link to the latest review.
Please note: After installing the app, you have 15 mins from Marketplace to request a refund. The app REQUIRES an additional download of approx 1 hour on WiFi before you can try it. Your window for refund will expire.
Considering the application is substantially different than the advertisements and screenshots, we consider this to be FRAUDULENT activity with the intent of STEALING users' money and preventing a refund by circumventing the marketplace's intent of permitting a user 15 mins to try an app before the purchase is permanent.
BTW, "all sales are final" NEVER protects a vendor from selling a product that is defective or substantially different from its advertisement.
