Query: Bad description on Amazon

I don't know how this device works, because I can't install it in my German car. Amazon fails to say you need a special connector for European cars, which costs $50. Amazon also fails to say you will need to spend $60 a year, after the first 15 months, to subscribe to a traffic radio service that will make this device work. If you travel a lot, you may need to spend $60 many times over to get the radio signals in different cities. Misleading advertising!
