If there’s any suggestions you could make, that would be helpful, but i’m losing patience rather rapidly with what is otherwise a decent car.

so, a, can the problem with the ‘disc accepting’ mechanism be sorted? b, is there a way to connect up a usb lead to the head unit using the 5 disc changer connecting cable (as you can with the rt4 and rt5 as i’ve seen in your previous posts) or, c, would it be easier to just chuck the whole lot and go for an aftermarket headunit and not have the screen working, as the only thing that would be missing is the clock and outside temperature. i presume this is because the header is ‘trying’ to do something with the disc but is unable to, thus, using more power and creating more heat. the radio/phone etc is ok, but after a longish run the system is overheating and comes up with various messages such as ‘volume reduced due to overheat/system will shut down/telephone stopped working’ etc. Hello there, i’m hoping you can help….i have a 53 plate 2004 307 sw with the rt3 head, 5 disc changer and full colour screen….the changer accepts discs but won’t play anything, the head unit works fine apart from it won’t pull a disc in so won’t play a disc.
