Hello

would like to know if there is a easy way to add a dab radio to the stream hu.As it display rear parking sensors the ac display which don't really want to lose.Dealer offered a kenwood unit but not at the figure he quoted and couldn't guarantee of keeping the display sensor etc from working I ask the forum for any ideas not really any good at practical work unless it's easy and straight forward to do many thanks 

What car are you planning fitting the unit to?
 

2006 Octavia has no mfsw 

I doubt any OEM unit (Columbus, Amundsen +) will keep the display data you want to keep. In fact I don't think anything DAB will manage to do so due to the age of the car unfortunately.

There are plenty of Android touch screen units on ebay that does heater controls and reverse sensors.
