Sony DSXM55BT Bluetooth Marine Digital Media Stereo Receiver SiriusXM Ready, Single DIN

Sounds great

Easy to install and sounds great

Install it on my motorcycle. Receiver quality and function are good. Great value for the money

Just installed in my boat and it took some doing because the specifications given are incorrect. It states the demensions are 8 x 7.06 which is incorrect. It’s much smaller than that. I had to add a cover and enlarge my opening to fit the cover. A lot more work than I anticipated. Turns out the specifications are the size of the delivery box. The unit seems very good other than that.

About the only negative I will mention is that the connection lines are kinda light gauge, probably <14g. It has a 10amp fuse and I'd say the wire would melt before the fuse would blow unfortunately. Why be so cheap on the connection wire when the rest of the package seems quite adequate? How much could the next size or two up actually cost extra? Otherwise, it's a reasonably priced unit for a 19ft Yamaha SX192. Display is easy to read and operation is pretty straightforward. If any quirks comes along I'll update. Can't talk of longevity, but here's to hoping. One star off for the light gauge connection wires.UPDATE - after two summer seasons of usage this unit is working VERY well. It pumps enough RMS to feed stock JBL 6 1/2" speakers x 4 on a 2015 Yamaha SX192. Completely satisfied as the OEM Clarion, if available, would be >$200, and IT only lasted 3 seasons before giving up the ghost. Although the wiring, as previously mentioned, is somewhat a light gauge, it's still providing adequate "bump" to the speakers so I cannot complain. Bluetooth connection is stable to Android, cannot comment on Apple connections. There's NOTHING to dislike at the $100 price point. Bumping up my rating to 5 stars!!!!

Sony claims this is the replacement to the DSX-M50BT however they fail to call out that the pre amps are now only two channel with the previous other 2 channels being stereo pre amp out for a sub!Who in their right mind would want a two channel head unit with a stereo sub pre out!!Sony claims not false advertisement when it’s not called out that they went back to 1960 and only have 2 pre outs…. Who would expect any pre out head unit to be only 2 channel??The fact that Sony would even produce this POS, and then claim it’s a direct replacement for the DSX-M50BT is just complete BS!! So what you’re supposed to just use a couple Y connectors? How’s that 4 channel separation? To top it off this is a marine head unit, if anyone has installed marine stereos they know it’s not exactly easy to just run new wires, so using the amp side is not an option nor what the system is set up to use…Was hung up on by Sony national support because they could not answer any questions and claim it’s not false advertising…. It’s stupid and whoever thought this was a good idea should be fired.2 channels and a sub… I’m thinking whoever has only 2 channels isn’t going to have a sub….I was hoping by calling support that through the UI there would be a way to have the stereo sub frequencies changed to full band and use as the two other channels, but they said no…Stay away from this, it’s a waste of money, unless of course you have 2 speakers and a sub.

ok so install was a little tough without the exact same wiring harness. But still not bad. We were pleasantly surprised how good it sounds in our boat. Great upgrade from our old radio with no bluetooth connectivity

Please be aware if you plan to use this head unit to output 4 channels to an external amp. Incredibly - it does not!!!I purchased this unit to upgrade my older Sony (DXS-MS60). It does not provide the same functionality. The '2 PREOUT' and 'x4' with this unit comes with caveats.As you can see in my pic, the 2 preouts are REAR and SUB. They are not for Front and Rear as with my older Sony, and most other head units with 4 channel capability. In short - the REAR outs means ONLY two channels available for external amplification. The other outs are for a sub. 4 channel functionality on this unit only applies to the INTERNAL amplifier!!!!!!!Not sure why they restricted the RCA outs to only 2 channels when the unit is processing 4 internally. I thought I was missing something , so I called Sony customer service. After being put on hold several times and about 30 minutes explaining to the representative my exact concern, the above indeed was confirmed - the 2 PREOUTS do not provide 4 channels.Do not make my mistake. I purchased several months ago, and only recently had a chance to install. So not only did I miss the Amazon Return window, but the Sony representative confirmed they would not accept the return because the unit was not defective. I guess I'm stuck and will keep for a future 2 channel install. Chances of my new 4 -channel unit being a Sony = ZERO.
