I bought this App figuring that the co-branding with AMA (American Motorcycle Association) made it a worthwhile product. It is not. First you pay a couple of bucks for the App only to find out AFTER that you have to subscribe to an expensive service to get the features advertised in the App to work. I deleted the App and wrote off the two buck App fee as a lesson in misleading advertising. If it is too good to be true, then it is not true.
