Hi! I've purchased one of these today. I would like to upgrade to/install/convert to a dab radio......have you done this & if so, do you have any advice or recommendations as to the best way to do it please? I suppose an alternative is to purchase a conversion kit. However, if the function is potentially available I'd like to investigate installation to integrate it on the car system - the 'mw-dab' button is on the console but my model only allows the mw function.....unless I'm missing something, which is highly likely!
