I think thats the only way Tim, to get permenant live connection for radio. The problem is ignition has to go full twist 3rd pos for radio to come on, which means all electrics come on inc fuel pump & other blemin things.
Anyway interior all clean now, hoover, dash cleaner sprayed everywhere, seats cleaned with damp cloth & leather cream slopped on. Autoglym leather cream IMO is needed this time of the year with temperatures rising & Nissan leather a bit crap
Thanks for suggestions guys & gal!
