One of my mate has lent me a stereo with DAB+ facility + mp3 etc. This DAB+ antenna needs sticking on the windscreen and running the cable all the way from there to the stereo. I could not find any proper information to do this, not even on youtube, does anyone have any knowledge in installing this. As this seems to me lil scary as it need removing passenger side front panel and then there is (I guess) some Air-Bag thing as well. Step by step instruction would be really helpful.
