Opinions wanted Posted in multiple groups as I reckon the odds of getting a response are fairly low Has anyone personally got either of the two units below as a headunit? If so would you care to give your opinion/thoughts on it - pluses and minuses please. The reasons for going this route are - - too many tales of Android units not living up to expectations, not updating etc etc. - all we need are CD/DVD, BT, DAB+, Reversing camera. Our satnav is Copilot on a tablet and it is staying there as it is not Android Auto compatible. https://www.pioneer-car.eu/uk/products/avh-a240dab/specifications https://www.kenwood-electronics.co.uk/car/nav_mm/mm/DDX317BT/?view=details Thank for any info you can provide.
