Thanks for the suggestions, for all they cost now I quote fancy a new single Din, but would like DAB. The bluetooth adaptor would wok but I quite like android auto. I'm still to decide on a phone mount, most likely window quad lock suction cup or ram mount combo. The speakers, I'm sure I can get better quality - the Clarion is quite weedy. Sub - my thought was a triangular foot box, foot rest kind of set up, maybe overkill.
My 59 made did with a bluetooth speaker in the dash shelf!
