To install:
Installation should pose no problem for technically savvy. Assembly instructions is not with !!!
On the blue cable of the adapter terminal of an ISO connector is fitted as they are installed by the side of the vehicle in the ISO connector.
That is actually one should from the radio harness of the car an Iso terminal drawn from the ISO power plug and insert it.
I have just a current thief on the blue-way cable which comes from the radio, clipped and clipped the antenna adapter between.
Works flawlessly.
I live in a village where I "Planet Radio" previously could not think of such as transmitter.
With this adapter, I really have a better reception than worlds without that I would almost say a virtually trouble-free.
All in all a very good investment, the 7 really worthwhile.
