Hi guys,
Firstly am a newbie to the forum so hi to all, just bought a rev 5 t-bar and loving it so far

got a couple questions though, sure they've been asked before but can't find the answers!
Firstly, do active systems make fitting an aftermarket head unit difficult?
Also, I'm wanting to fit a dab stereo, so obviously it will need a dab aerial.

I believe there is a converter I can buy so I can still use the electric standard aerial, would rather that than have to stick something else in the windscreen, but are the converters any good or not? Also would the converter still let it go up and down? Or am I better sticking the thing in the screen?
Not too clued up on new fangled digital stuff

Thanks in advance

Andy
