I had a subpar brand unit that failed in my golf cart. I replaced it with this Pioneer MVH-S230BT when it came up on a flash deal. I have been a fan of Pioneer products since the 80's and have never had a problem with their head units, speakers or amps. I still use a 30 year old Pioneer amp to drive two 10" subs in my truck. This MVH-S230BT is a basic non-CD head unit that fits my needs for my golf cart with 4 speakers. I may need to add a subwoofer and this unit has the RCA outputs for an amp/sub. The Pioneer units that I have owned in the past have always had better than average FM tuning and this one is great as well. I get much more FM channels now. All other features work as they should. If you are looking for a quality brand basic non-CD digital media head unit, then this one is recommended by me.

Fast shipping. Easy installation. Sounds good.

The positives: solid update / replacement for a 24-year old Pioneer on my boat. Easy install (note that it’s a full sized single DIN) and solid audio output. Handles my 16gb of usb-stick music with a workable menu system.The meh: it’s a bit on the pricey side for what it is, and the Pioneer audio app that it wants to see for a phone connection is a tad clunky; I haven’t quite figured out if it’s possible to just connect a phone for basic music streaming without using the app (it demanded the app, and I just went with it). On the positive side, having Bluetooth control of the radio (volume, fader, music selection etc) via the app from the flybridge is nice.Overall, would buy it again.

Replaced a garbage Pioneer s21bt with this model. The s21bt being a $40-$50 head unit, the quality definitely goes up with price. Originally bought the car I installed this in as a throw away car but its been through a rebuild and still here after 5 years so I finally decided I needed a better radio in it.Bought this Pioneer s322bt as a test to see if more money meant better quality. Just wanting Bluetooth audio, all single din systems do the same thing and output the same power unless you spring for a "high power" system like that big 100watt rms Sony single din or a double din with a screen. Still, 95% of head units max out at 50-60 watts per channel and 12-15rms. Their are "high res" units but then the quality of you speakers and wire come into play if you want to hear a real difference. I simply want noise, Im already running good rated Pioneer speakers all around, no dedicated sub, so pretty much any single din will do as Im not want to spend double din money going down the rabbit hole chasing a high resolution screen and features like wireless android auto and other big double din features.So here I am with this s322bt. I mentioned the "volume knob" and this is my biggest gripe about the cheap Pioneer I used before this. The volume knob on the previous one was trash, spin it too hard or fast and it freezes up, very irritating. This one here has got a great volume knob and doesnt skip or freeze if you spin it too fast. This also seems to keep time accurately also. Back lighting is super bright and is appropriately "dim" when you set the brightness down. This unit also hasn't unpaired from my phone at random. This s322bt is an all around solid value.

For the $, this is a killer radio. The bluetooth is great for music, and even better when it comes to call quality. The mic is actually in the face of the head unit (no wiring an external mic up into your headliner). Everybody told me I sounded clearer than factory Bluetooth car radios. The radio feature didn't work great in my 4Runner, but I think it was the 4Runner's radio antenna. Would recommend this to a friend, for sure.

In the last few months I re-riped my entire CD collection to a home database in the FLAC format. A number of years ago I had done the same thing but to the AAC format. Well, comparing the AAC to FLAC on several systems at home it was clear to me that FLAC is the way to go now. Much improved sound quality. Cant tell it from CD, which is the point.Trouble is the older Sony multimedia player in my Van only supported lossey formats like AAC. Looking around for something very similar to it, but with FLAC support I came across the S720. I picked this particular model over the other Pioneer choices with FLAC because it also has the other features I had come to need with my Sony (DSX-310BTX), had a couple more, and it fit into the same 1 DIN standard depth slot in the van.Installation was typical. While the wire harness color code is standard so in theory a straight swap in should be possible, the actual connectors are different, so i cut out the old harness and wired in the pigtail (minus the speaker wires) that came with the Pioneer. I use an Alpine 4x45W amp for the JL Audio midrange and tweeters and a Sony 300W sub amp for a Pioneer subwoofer so do I used the pre-outs from the S720. I also took advantage of the of the Pioneer internal 3 way crossover not in my Sony to eliminate the JL Audio passive crossovers. Funny thing about the S720 pre-outs...The Front/Hi out is the middle pair, the Rear/Mid is on top, and the sub on the bottom. While the chassis is labeled with stampings to this effect, it is nowhere in the user manual and pretty hard to read when the head unit is half installed. I initially put the tweeters into the top set and mids into the middle (which is logical to me, and in fact the way most similar units including a Pioneer or two do it). It was pretty obvious to me when the tweeters were trying to play midrange.Playing FLAC files is not as straight forward as one would think. First issue is that the CD ripper/FLAC converter I used didnt produce files that the S720 recognized as music. I used EAC with the XPIS FLAC plugin, which works great everywhere except in the S720. Eventually I found that by "re-converting" my existing FLAC files to FLAC using the dBpoweramp app, I was able to fix whatever the Pioneer doesnt like about the XPIS conversion. It was probably related to file info and not the actual compression. Once that was solved I next found there is some upper limit to either the number of files or the size of the end package of files the S720 will support. I know that when I put the entire reconverted set of files (72GB and 3800 files on a 128G flashdrive) I get an Error 19 when plugging the flashdrive into the S720. When I deleted a number of folders and was below 64GB (not sure what the final file count is, but still on the same 128G flashdrive), it worked fine.Next I went thru the S720 driver time alignment, then a leveling and EQ process using an Android based app with white noise, spectrum analyzer and calibrated mic as a reference to get a relatively flat frequency response. Time consuming, but worth the trouble.The best part is how great it sounds. Not just because of the FLAC format, but even AAC and analog sound better. I am sure the ability to time align and fine tune the eq contribute a lot but it also looks like Pioneer did a nice job of implementing the digital and analog in the head unit.Complaints? I cant believe head units havent begun using non-volatile memory for configurations. Pull the power and you get to start over. This sucks if you sent a lot of time setting it up. There is literally no installation manual. You get a quick start guide with the unit, but it doesnt even have a picture of the I/O on the back. There are a bunch of videos on the Pioneer product page for the unit, but they only cover the connector wiring color meanings and a bunch of how-to's on various functions once you get it up and running. By the way, these videos are way better than the user manual explaining how to set up and use features. Finally, who needs a really, really large BASS button? Its the second largest function on the units face next to the rotary encoder. So far the Smart Sync app is a mixed blessing. It makes it possible to find my way thru the FLAC files in short order, where the front panel interface is hopeless (all the music files are presented on the S720 as though in a single folder and in alphabetical order by file name). My biggest complaint with it is that it seems to want to take over all functions on the phone and it puts itself on top of all other apps. I found a way to prevent it from automatically starting up when the phone connects to the head unit, but then it wont even connect after the bluetooth connection is established. I cant seem to locate the 31 band EQ that some of the literature touts is available thru Smart Sync, and when Smart Sync is connected I cant change the contents of my custom EQ. I hope this app is a work in progress and not what Pioneer considers THE app. It needs lots of work.
