Hello Jetboaters,

I would like to ask our group, who has replaced their stern remote stereo of Polk Audio PA4A to a Polk Audio UMC1?
is it compatible ( in terms of hardware size installation at the same spot where the old polk audio PA4A was installed and system compatibility ) with the CONNEXT system of 2016 Yamaha 242 Ltd S e-series? Before i purchase this Polk Audio UMC1.

Thanks so much in this group in advance.

I believe they are both interchangeable, it has been discussed here before. If you do a search here you should find many posts on it

Please be sure to post your results. I've also found Polk's tech support to be decently responsive....might ask them directly.

Look forward to hearing your answer as mine doesn't have much life left in it!

Circling back on this old thread to see if anyone has any updates. I have the PolkPA4 and I need to replace it. Ideally with the Polk UMC1RTL which I understand is the model replacement radio from Polk. I talked with ASA electronics support and they said it should work with the existing harness, however no one can tell me for sure if it will interface with the Yamaha Connext system as the PA4A does. I have a 2018 AR240 and would like to no if anyone else has made this installation? Would love your feedback and advice.

Did you ever make the swap? I'm trying to determine if it will work with the Connext.

I did not make the change. I was able to get my stereo to work so I didn’t need to swap it after all. Sorry I couldn’t give you more info.

Wondering if any of you ever tried this replacement? Any feedback would be great.
