I am sorry if this question has been raised before. I have just bought a 2008 Peugeot 407 which has had the radio replaced by an after market head. I don't seem to be able to set the clock etc. and I don't have a trip computer. Would this be because some of the functions went with the removal of the original radio/CD panel.\r\nIf so, is there an after market solution that gives me a decent radio with MP3 input and gets back the trip computer or do I have to go back to the original Peugeot set up?
