Anything Kenwood that has a remote input should still work with the transom remote. I will say, I haven't used mine for 2 years and don't really miss it much. I put in a wetsounds EQ with BT dongle from JL audio and just play off my phone now. Only downside is can't change the volume from the water, but I don't usually mess with volume much anyway once it's set to where I want it. On the plus side, my 9 year old can't be obnoxious and change the stereo from the water anymore, so that's nice.
