I am planning on swapping my current F910BT to a F70DAB. The F910BT is installed in an alfa romeo 159 and works with steering wheel controls and it goes into the reverse screen when reverse gear is engaged. I would like to know will I be able to use the current wiring and microphone that are in there or will I need to buy new ones for the F70DAB?

Also, will I need to purchase an additional dab aerial to work with the new unit? If so, any recommendations?

no, u can use the same cables, maybe u need to change the mic... confirmed from Pioneer support, if you don't have DAB cable then u should buy a new one...i have also AVIC-F70DAB and i love it
