I have a KCA-RC100MR remote, I purcased, thinking it would work wit the factory kenwood deck, It does not. Paid $50 on E-bay for it, jsut want to recoup some costs.. so for sale for $30... THis apparently will only work with marine head units... Also, I cut the wire, thinking I could splice it in, but I cant, unit still works fine, and is brand new. I have both ends of the wire I cut. $30, thats why the low price...
