The only problems with addons is that they are usually stored onto one channel of your FM band and you use your steering wheel remote or seperate remote to flick through the channel. Factory or internal DAB from an after-market head unit has it's own DAB channel that you store your favourites on or search through the same as you would on FM1 or FM2 etc. Maybe I'm wrong though and the unit will give you the option of a separate DAB channel once the add on is plugged in?
