I have fitted a Denison dab module via the usb socket on the tsn 510 radio in my avensis t27 tourer year 2010. I am using a glass mount aerial fitted to the near side side window but this makes it look a taxi or company car. I would like to change the roof aerial to inc dab. I was wondering if the roof aerial fitted to the latest Avensis models which have dab radio units fitted as standard could be fitted to my avensis. I know I will have to run a new dab cable from my dab unit to the roof to connect to the new aerial. Has any one done this or can give me any advice.
