i was bored of the classic fiat radio cassete player so i bought a new rds radio cd from lidl (99 euro).fiat helped me to uninstall the all and i installed the new one my self.i needed only one antenna adapter,and another plastic cover to surround the cd-player.the old one was 2x10 watts and new is 4x40 w .i connected it and it works with front speakers.the rear base has a cable on each side but i can;t find the other end at the radio socket under the dash(only four pins for frond speakers found).Any ideas would be apreciated........!!!!
