radio wasnt working in the car (2008 197 cup), so i took it out and found that only 3 parts were connected, black housing, grey housing and the aerial. after rooting around i found a set of wires with a yellow housing so i connected that and it finally let me put the code in a get the radio working. but, there is no outside temperature showing. there wasnt before either, the display would just show the time and nothing else. so i took out the radio on my mums 2007 rip curl clio and found that hers had a set of wires in a blue housing as well as the grey, black and yellow one mine has. why does hers have 4 connectors and where is my temerature readout! i know this is a small thing but i like to have everything working as it should. any help with this would be very appreciated.
