I bought a new LG cd player for my 1996 Peugeot 406. I removed the old Clarion tape/radio, and there were three connectors at the back, plus the antenna. Two were iso connectors and one was something else, which I presume connects to the stalk, for the sterring wheel control. I ignored this one and connected the two isos to the two iso plugs in the back of the LG cd player. The cd slot made noise (like it was accepting or rejecting a cd) and then nothing. THe unit wouldn't turn on. I replaced the Clarion but it wouldn't turn on either! There seem to be a lot of adaptors available for post 99 406's, but they seem to use a non-iso connector. Can anyone tell me what's going on? Do I need an adaptor? Thanks Richard
