Died in less than a year.
I bought this unit in the middle of last summer for my Jeep and this spring I can’t get it to put out any sound. I checked all the wires, fuses and all looked good. The deck powers up and seems to function properly just no sound. I can’t get ahold of Sony because of Covid, not sure what to do now.

Blue tooth issue
I bought this radio last year to put in my motorcycle. It worked about four months and then all of a sudden only thing I could get out of it is the CD player and a USB player. I’ve tried every which way to try to get the Bluetooth to work again and sink but is unable to sync it just says that it’s not there. For the money that I spent on it I would’ve expected something a lot better disappointed customer sincerely

Unit Resets (Turns Off): Using Ph BT & High Volume
Sep. 2, 2018: I just bought this unit and installed it in my boat. I have the exact problem as described by the person on the 8/22/18 review post below. I bought this unit for the same reason he did - it's the highest output (watts) marine stereo you can buy without buying a head unit with a separate amp.

Problem! When you are playing music off your phone (I have a Samsung Note 8) connected by BlueTooth and you put the phone volume up to maximum output or 1 click below maximum and then you turn up the volume on the Sony MEX-M100BT after a minute or so, the head unit will shutoff and reboot; then, you need to restart everything.

Also, I agree with the 8/22/18 post below, the work around is to put your phone on about 75% or, I found, about 2 clicks into the red zone. Then, the system seems to work great, but then the max. volume is not very high!

Best head unit ever. I have 1 in 3 of my cars!
This unit is great all around. To the gentleman that wrote about it resetting, I too had this problem and had it installed professionally. However, I personally did some research and after reading the manual more closely this unit requires a dedicated power wire direct from the battery. It does say that in the manual and on the Sony website. I had them run this wire (despite their disbelief and pessimism bc they had never heard of a unit needing this they grudgingly did it and low and behold it worked great and still does. I’ve had minor hiccups with them as again I have 3 of them but it has been a simple fix and something i had done wrong that caused it. Try this idea out with the wire straight from battery and see if it helps. Good luck!

Great sound / poor design
I purchased this stereo because it seemed to have the most overall power of any marine grade stereos that I could find. My goal was to get great sound clarity and volume without having to purchase a separate amplifier. This unit somewhat did the job. Let me explain.....

So after first installing the stereo it seemed to work well. I had great volume and sound clarity while using the tuner / stereo. However, once I started to play music through my phone using either Bluetooth or auxiliary I started to run into problems.

If I had the volume turned up over 30 on the head unit, the system would reset after playing for awhile. I double checked all my wiring and it seemed fine so I contacted Sony support. They were semi-helpful and we tried doing a hard reset and firmware update. The unit continued to work just fine when running the tuner / stereo no matter how high the volume, but would reset when playing over Bluetooth or auxiliary once the volume surpassed 30. It appeared to be a faulty unit.

After working with Sony support I had a new unit shipped to me. The new one arrived and I installed it. It worked fine for the first 7-8 minutes and then the same thing. So now I was forced to contact a professional to see what the issue was. He confirmed all wiring was good and was at first stumped himself. So I demonstrated how to reproduce the issue. He hooked up a voltmeter and we watched as the system would reset. Apparently if the voltage to the unit dropped to 11.8 volts or lower, it would reset. This was very surprising to him since he said in all of the 100's of installs he had done, he had never seen a stereo so sensitive as to reset with such a small drop in voltage. Most wouldn't reset until the voltage was in the 10.x range.

The work-around isn't ideal, but will work until Sony makes an update to firmware (if that will fix it) or issues a recall. The work around is to only set the volume on my phone to about 75% output. This seems to keep the unit from resetting since it doesn't try to pull that extra power to output to the speakers. It is disappointing since I feel I am not getting all the benefit of the built in amplifier for which I paid all that money, but at least I can listen to my music without it resetting every few minutes.

Other than that, the controls and settings are not intuitive but after reading through the manual and playing with it a little bit I can now navigate through the menu fairly easy. Of course, with how small some of the labels are on the unit a bright glare can make it hard to read the small print as well. Sony tried to fill a void that was in the market with a powerful unit, but didn't put the amount of testing and thought into the design that they should have with the product. If you are dead set on not running an amp with your stereo this will work. However, if I had this to do over again I would have simply purchased a less expensive unit and an amplifier to go with it.

One year of service very happy
I bought this for our sailboat. Powers 6 160 watt RMS marine speakers of very good quality. The power draw is absolutely minimal and it pumps out lots of loud and clean sound with a great dynamic range. We don't have a sub-woofer on our boat so I can't comment on using it to power one. I wouldn't consider another stereo for a sailboat.

falls short on music adjustment
I bought this radio off of a friend to put in my ford focus with a full system behind it. I love the positive display, I haven't had a hard time seeing the screen even in bright light but i would have liked to have seen separated high pass filters for front and back and i would have liked to have an actual db number for slopes instead of modes (1, 2, 3 etc.) i find it hard to use without reading the manual first. Also, the built in amp is fantastic and without boosting modes on there is little to no distortion even all the way up in volume. very very happy with the sound quality.
