Tried to avoid Cancheck problem by buying LG CD player, had it fitted by Halfords with Halfords fascia plate. CD player worked ok, but was on even with key out of ignition, swiching of cd cut display but suspect unit still live.
result battery totally drained if car not used for two days - halfords unable to resolve, said punto provide live to unit at all times only fiat supplied cd avoid problem. unit removed money back but now driving in silence while pondering what to do next
you spent loads on car & loads on stereo so why not get it installed correctly
