RPM Car Audio

Bloody useless, been back nearly every week to sort radio out ... 1st time, cds wouldnt work, gps wasnt working, they fiddled, worked briefly, boom a week later stops.. replaces the radio unit, yay cd, gps working...
Week later clock loses time, go down, reset it, works, turns car off, next day get in car, lost time again, go back, they put new unit in, reset everything... surprise surprise clock lost again...
Went back to car yard, as new car, they have arranged to have a totally new radio/ brand of radio to be put in...
I honestly for wat we were charged will not deal with this company ..... they can sort it out, but in future we will not do any more business..
Very pissed off..
