Hello, for most certainly a stupid question, but I am completely undefiled stuff car radio. Does this thing fit herehttp://www.clarion.com/…/en-de-product-pf_1170603795514.html with reasonable effort in my MK7 tournament, year 97? Have at the moment still the factory radio in it (name follows), which occupies the double shaft. But slowly gives up the mind. I assume I need an adapter for the shaft. I can take over the wiring for power, antenna and speakers, or do I need adapters, etc.? Thank you!
