i do not have a transom remote but from everything i have read, i believe there is a Y connector to hook two remotes to the HU. If u can't find the Y connector the steering wheel control wire is only one wire. it seams that u could connect more than one wire to it and get the same function w/both remotes.(try doing a search on the forum for " dual remote hook up") The kenwood 107 remote IS NOT a one wire hook up. the 107 is a multin pin pig style that has a seperate hook up in the back of the HU. The remotes u have are just a one wire hook up to the HU. i cant vauch for both, but i know one will work for the 440u. the 440u also has a usb input in the front for ur ipod and full controls of the ipod from remote or head unit.
