[FYT Android Head Units] rudy626:
#1 If you are looking at Joying snapdragon units I believe they are all button less, which not having swc is going to be a pain in the butt as you will have to click on the volume icon and slide the volume up or down, hard to do while driving. But other. Than that it's solid. People complain at the fact that the 625 is an older chipset but this is a head unit not a tablet porformance is more than enough for radio stuff. One other thing people don't look at is LTE bands, the snapdragon units support band 4 and 12 which are big in the T-Mobile network, but i will note my Joying headunit has a 4g issue so haven't been able to experience a fully connected drive currently still going through customer service to rectify this issue.

#2 The screen is bright I haven't had issues with not being able to see the screen content. That being said it glares a lot, my unit being mounted 100% vertically reduces the chances of having glare issues but i can see it being an issue on my Avalon where the screen has a slight angle facing the windshield. When I had a Joying unit in that one glare was impossible to combat making the screen useless around mid day.

#3 you can download any android app as on any android device but you will not be able to pair a controller. I tried pairing my Xbox series x controller for hours, couldn't get it to connect, it seams Joying changes something in the Bluetooth interface that voids being able to access the main Bluetooth settings. For me that would make this point useless. I haven't tested USB connection only Bluetooth.

#4 This can be true. There are a lot of generic android radios for under 100 bucks that use the cheapest audio chips to get a product out and sold. This gives you the Android experience but overlooks the audio experience. Joying on the other hand is fairly expensive for a Chinese company sourcing android radios. The reason for this is they implement higher end components to also improve audio quality, and although it is not on par with high end pioneer or Kenwood's it does compare to radios in it's price range. In most cases if your car has only 4 speakers meaning 1 on each door and no factory amplifier the Joying will improve your sound. If your car has a premium audio system from factory IE. JBL, Bose, mark Levinson ext where you have 8-12 speakers in your car and bypass that with this radio it will sound like crap. It would sound like crap with any radio as factory amplifiers have different impedance and crossovers to compensate for special speaker wiring that your radio won't have. Another thing is if you plan to install a sound system in your vehicle you are told to stay away from these units as they distort at low volumes not allowing you to maximize the audio. Also true of old Joying units, these new ones get pretty close to 3v out of RCA before distortion at around 75-80% volume. I tested them with my DM-RTA. Granted this is not 4v as standard by pioneer, Sony and other headunit manufacturer it should suffice and or can be improved by a 200$ line driver. At 700$ still cheaper than any large manufacturer radio with similar specs as in size and functions like wireless car play And android auto.

#5 This I don't know but would advice to ask and see if you are able to pair a Bluetooth model and phone at the same time.
