Hi, so I have a Ford KA (2000) and decided to swap out the standard cassette player (for obvious reasons) and put in another radio. I picked up a Sendai CD-789 and the necessary adaptors to compensate for the KA's wiring design. I took out the old player and fitted the new one fine - except (after working at first) a few days later it has stopped working. I took the radio out and fiddled with the wires with the power on (and the lights on the head blinked) which leads me to understand that the radio itself is working and isn't the problem. It seems that the ISO connector that came with the radio doesn't work, though I'm not sure - does it sound like a dodgy connector? What can I do to fix it?
I have very limited knowledge in this field and would appreciate some help!
