I having been using this unit in two different Lexus Vehicles, 2014 Lexus RX450h & a 2013 Lexus ES 300h. It's the only head unit that I could find that would allow me to install it on the back of the rear seat or in the trunk, while at the same time use an app (Sony Music Center) to control almost all the functionalities from the driver seat. Most professionals or DIY installers know the challenges that these newer vehicles come with, where the head unit is combined with A/C and other important vehicles functions, you can't just swap that radio out like back in the days. Rest assured that Sony RSX GS9 represents hope, other than the power wires that I tapped into behind the OEM radio, everything else left untouched on the dashboard. I am a DIYer and I single-handedly insulated, wired, mounted and tune the entire system myself. The sound quality of the RSX GS9, when properly tuned, the audio reproduction is staggering. Sony has really outdone themselves this this time, so much so that they have yet to build another unit to replace this one.
Pros: Flexibility with installation Hi Resolution Playback up to 11.2 MHZ Built Quality
Cons: A wired remote screen would have been nice, but not a deal breaker.

Don´t compare this head unit with the rest. We have only 2 head units in this level (this one + Pioneer P99RS) If you are looking for conections, or fancy stuff... go for it and try another models. But, if you are looking for sound quality this is your option. Yes this Head Unit havent some features, have lights, havent big numbers to sell. The best of GS9 is the USB-DAC, Apple music or Deezer or whatever you use, will sound absolutly better. I Listen my Focal Utopia with crispy mids and highs... i can hear details that never heard. Sometimes i turn signal to compare USB-DAC vs regular USB connection for iPod... and you can hear hows distortion disappear everytime you change. When we only hear regular USB for iPod we never learn that we have upper levels to enjoy accurancy music. Even... if you enjoy rap, hiphop, reggetón you will experience different level. Of course, if your music is the jazz, blues, vocals... you will hear the violin just infront of your eyes (sq listeners knows why im sayin hear with eyes) So... dont take serious those reviews, if you want a radio, just want features, easy connection, quick response... go... and try another option. but if you are serious about SQ ... you have only two options... this one or the Pioneer P99RS. But i choose this one, cause is discreet and sober. When people see this inside your car, they never imagine a kind of mounster that they have in front.
Pros: Sound Quality. And you dont need more!
Cons: none.... (people says... price????? Toyota have a price BMW have a price Maserati have a price if you want a Maserati, you need pay a Maserati. You will not buy one with BMW or Toyota price. You have the same here, if you want Sound Quality, you need pay for GS9. So, no Cons for this HU

The App to use this headunit is very slow. You are constantly reconnecting to bluetooth every time you get in your car. If your bezel/trim breaks, Crutchfield will tell you to ask Sony, And Sony will tell you to ask their 3rd party parts distributor, and their 3rd party parts distributor will tell you to ask your installer. Your installer will tell you they only have generic and not the color matched bezel/trim that the Sony RSX-GS9 originally came with. This is ridiculous for an expensive receiver that has only been out for ONE year.

I was very hesitant on buying as I already have a helix dsp pro. But I will say it is a nice addition to processor with optical out and plays any High-Res media from my Sony zx2, iPhone and stick drives with awesome sound quality. The tuner even sounds great. If your goal is no frills pure SQ and you listen to mostly High-Res media than this is a great choice as I don't believe there is anything out there like it! BT is probably one of the best I've heard. songpal app is easy to use as well.
Pros: SQ, Plays all High-Res media. Zero Noise floor!
Cons: I'm in my car to much!

-very nice head unit -VERY well built, solid construction -seems like this will last many many years to come -running it with a Zero3 amp, Fosgate wiring kit, and Focal PC710s -what i like about this head unit, no built in amp, very hard to find at an affordable price. -also the clarity.. WOW... what an improvement. even older music files sound much cleaner, something you have to hear to appreciate. -while i am not a phone gadgety person, the SongPal is nice -the remote is easy to use as well -the built in EQ settings are actually really nice too -unit has some nice options and features -i bought it for clarity, and to play off a USB stick, meets my needs just fine
Pros: CLARITY construction... well made piece
Cons: i believe this is 4v preamp out as i had to slightly up the gain on the amp

I wired up the unit and was a little lost. There's no menu button, so you need the remote to access most of the features. I began to pair the Bluetooth, but an app was required and iTunes would freeze before telling me which app (it's Songpal, you need the app to pair). You can adjust sound settings through the app which was nice, but any adjustment to the 10 band custom frequency causes the audio to clip out for a second. Real brutal on the ears if your tuning at a higher volume. I mounted the unit in my glove box, so the screen and overall look didn't carry weight with me. But you can turn on off the the "DSEE" feature to hear the contrast on your hard earned dollars going into top end equipment. I couldn't hear any difference when flipping this on or off. But a fair argument could be made since the whole unit uses top of the line components, the SQ is pretty good from the start. If you have a bunch of lossless audio and the price tag doesn't scare you, it would gain you bragging rights to own this unit over others. But if your like me with 10,000 mp3s your playing from an iPhone, this won't give you a huge leg up over the other head units out there. 320 can only go so far. I did like however, the unit did cut back on hissing, which allowed me to throw more gain from my amp; which really pushed SQ . If your spending this money, you'd probably see better results in speaker or amp upgrades. Listened with 4 focal krx2's, fp4160, and k2 sub.
Pros: All digital from the ground up; once paired the Songpal app dials right into you phone and kicks you into your native player, very user friendly; no built in amp allows s direct and cleaner signal from your amp.
Cons: Difficult to tune (hopefully your only doing this once) with limited ranges; price seems double the value; sound quality is not greatly improved on mp3s. (I didn't try it with lossless audio)
