Review: Ain’t nothing wrong with it - Excellent unit for the price! Hade it two years, sounds great, Bluetooth works well, it’s user friendly. And most of all it’s not over-the-top. It’ll sync right up with your Spotify, Apple Music, and Pandora even though it doesn’t have touchscreen with apps. I love it!
Review: Got this after going through many other car stereos. Happy Camper! - Sheesh! After trying multiple other head-units (Android, Carplay, Android Auto etc.) I went back to my original "Mission Statement" - KEEP IT SIMPLE! This JVC does exactly what I wanted it to do and is very customizable on top of that! Sounds and features and even the phone works great through the Mic. Very impressed with this. Don't spend lots of $$$ on a high-end unit. (Well you can... but...) This JVC is very easy to use. - Especially in this day and age of touch-screen madness. I'm very happy with my choice. Simple to install and the directions are very good. Happy that some company still makes a car stereo that "Keeps things simple" and sounds great. I'm glad I came back to this one as it was my first choice to begin with! Great Stereo. UPDATE: One slight negative that appears during the day - The center display (Time, stations, Channel and info.) gets washed-out by the sunlight. Very hard to see and the settings are at "Maximum Brightness". At night it's great... Very visible. Daylight is very difficult to see.

### ⭐⭐⭐⭐ Good value stereo
*by S***L on June 28, 2020*

Got this stereo to replace my wifes 2008 Nissan Altima 2.5S factory unit. It sounded good, better than my 2008 Honda Accord V6 EXL stereo with a "subwoofer". I got aftermarket for that, amped and loud, but with many many car specific issues. Anyway, the Nissan stereo started having blank screen, partial text screen, can't change station, etc So I got this due to price. First double din, wanted for wifes ease of seeing it while driving. I used factory speakers, Scosche wiring adaptors (antenna also) and the Metra dash adapter. Wasn't terrific, but not as bad as some reviews lead it to be (I had to use a blade, file, and some glue). Stereo is good, a bit cheezy for me but wife likes it. My one issue is the antenna. Nissan (unsure of the new ones) uses an antenna in the back window with a powered unit to boost it in the rear passenger pillar. I didn't connect it, just used the rca style male to the back of the unit. Radio had one channel. I had to open it back up (cracked the shroud around the vents) and connected the blue/white stripe wire to the antenna adapter blue. The blue from stereo adapter to blue antenna adapter doesn't work. The wire is labeled P conn/ant P or something like that. The other is blue with yellow stripe and says remote. So in short, the blue antenna to blue with white stripe is the combo. Test the stereo first before you put it all back, lol This was my only hiccup though. Bluetooth mic sounds good for calls. It has the external one you put in the front A pillar for drivers side. AUX jack behind stereo, so run it left, behind the steering wheel and other junk, pull off that small panel on side of dash and run wire out, then up the pillar. I tucked into it, didn't take it off, but I got it dirty with my "inside the dash" dust (sorry babe). Clean your hands or put on gloves and tuck in with a clean flat head, putty knife, etc. Sounds good with factory speakers, bass on them is not bad for factory, but don't blow them. Now to figure out how to change the head unit color...so many tweeks but unsure how to make them stick. Haven't tried CD, but used Pandora and it was good. Calls are good also. Could have more descriptive info included, but will have to dink around with it. Again, probably better ones out there, but for good value stereo replacement on and older car...you can't go wrong with this!
