Hi there i have a 2011 lwb vivaro and im thinking of putting a dab digital single din head unit in. the current head unit it pretty much pants is it as easy as changing the unit obviously connecting back the steering wheel function etc im wondering if you have to change any facias or is it a easy swap over. by doing this does the orange screen become redundant? theres a video on you tube is it as easy as this? other question the aerial will have to be changed for dab is it easy to replace or shall i go for the windscreen type?
