    • Ain’t nothing wrong with it
Style: KW-R940BTS
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!

    • Got this after going through many other car stereos. Happy Camper!
Style: KW-X840BTS
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. ... show more

    • Looks great
Style: KW-X840BTS
Mostly got this because it looks good, but it also works great. I don’t play around with the settings too much, but the bass adjusts great. I wish it came with a frame (not quite sure what you call it) so it would look more flush in my 2000 4Runner. I probably would have to contact a car stereo website to find the right one. ... show more

    • Unbeatable value
Style: KW-X840BTS
I won a 100 gift card at work about 6-7 years ago,used it for this and just decided to give my review on this, as I was scrolling through old purchases. I put this in my Genesis coupe and it has been very good for a long time. Not the best, but you cannot beat it for the price. Kenwood owns JVC, and they've always made great decks. ... show more

    • Would NOT buy again.
Style: KW-X840BTS
Not my favorite, but it's working after some tweaking with the grounding wire. My next one will have a backup camera. Price was good, but I'll spend more next time. Throws random error code from time to time. Turning it off and on usually fixes it. I'll run it until it fails, then upgrade. Phone mic works great. ... show more
