Car bluetooth FM transmitter, Aux Bluetooth Car Adapter With 1.8″ Color Display, Fast Charging Dual USB Bluetooth Radio Adapter, Hands-Free Phone Kit Cigarette Lighter Wireless Car Music Adapter

Much better than expected
As this was very reasonably priced I hoped it would work, but with the expectation that it may not work fully or maybe not at all.
I was very surprised to find it easy to pair to my iPad via Bluetooth and through the aux socket. Sound quality is very very good and it works better than I could have dreamed
I heartily recommend this unit, not the cheapest of its kind, but it works perfectly for me with my Apple products and in my Z4

Good sound but no EQ Modes via Bluetooth
Easy to use plug-n-play.
Have connected device to car audio via 3mm aux cable (supplied) rather than FM Tuner.
Description and (thin) instruction manual refer to EQ Modes however these do not appear to work when connecting iphone via Bluetooth.
Notwithstanding lack of EQ Modes the sound quality is good.
Phone connection (hands free) provided clear voice according to callers.

Sound loss using Bluetooth playback.
I really wanted this to work well. It’s small and quite compact, the screen provides song details and car battery voltage. Not sure about caller info yet but when I made a call using WhatsApp it showed
Phone -> 10000000 during the call.
Not sure what that was about. Call quality was good though. The text is quite small.
Unfortunately the losses when playing music back via Bluetooth are terrible. When playing through the TF card the sound was great. Volume was the same as the radio but as soon as I playback via Bluetooth I had to crank the volume way up to get a similar volume. The losses don’t end there, the quality of playback via Bluetooth was awful too, whereas the TF card was perfect. There’s a menu when playing music via the TF card which allows folder or song selection as well as a random play function. Really useful.
Unfortunately the USB playback would not work. I returned it for another and got the same result. So I’ve tried two units now and have had the same result. Having to try a different brand now.
Hope this was helpful.
Update
Tried another USB stick and it worked. Turns out it killed my previous one which I had been using on another audio unit. Not sure how that happened but that USB stick is unrecoverable so a bit annoyed about that.

Half works!!!!
Music plays well in speakers. The phone option does not connect and makes a bad buzzing sound that makes it unusable.

Nowhere on the box or in the pictures or on the little instruction sheet that I say what Bluetooth version it is. Only in the product description here on the page it mentions at one single time casually Bluetooth 5.3. well hopefully that’s actually true. So far I haven’t had to do anything to make it reconnect it’s reconnected by itself every time. I do a lot of driving and my old one would not connect sometimes just enough to tic me off. My car with the key off all power goes down so I don’t have to unplug it or anything like that. I would imagine most cards are like that.
It’s weird it doesn’t mention anywhere in the instructions that holding the main volume button in well shut it off. That’s what it does for me if you hold it in a couple seconds. It’s nice to have that feature I wish my old one had that. But hopefully I don’t have to really use it if it always connects reliably. Not have to unplug my old one a little bit and then plug it back in to repower for it to connect when it decides not to. That was the main reason for upgrading is my old one was Bluetooth 3.0 and it didn’t always connect. So far it’s doing what I was hoping for. It sounds good and I only hear a little bit of staticky noise when my car volume is literally maxed out. And just a little bit under max. Normal volume I don’t even hear anything at all. It goes in snug in the cigarette lighter which is good. I wish I would have a button somewhere to change between blue, green and red led lights or something. That would be able to match most cars as my interior radio lights are a reddish orange. I tried the auxiliary and it worked although the supplied cable doesn’t really snap into my phone hardly but it still worked. But it can come out easy so I found a spare that I have in a drawer and have that just in case I want to use it. I haven’t tried SD card or the USB function yet. I suppose that would be the way to go to squeeze out the most quality you can with this. With auxiliary hooked up you lose volume knob control and ability to stop a YouTube video. Pressing it once will stop the sound for a YouTube video but not the video itself. It will stop a music player still. My old one did the same thing so I guess it’s some kind of hardware compatibility thing going on with auxiliary. I use Bluetooth most of the time anyway and the stop start function works for YouTube videos and music players.
So far I’m pretty happy with it and the sound quality is good and it’s been reconnecting like a champ which is a big plus for me. Don’t forget that if you hold the main volume knob in for a little bit it will shut off. I don’t know why that feature is not mentioned anywhere. Holding it in again will turn it back on and it reconnected every time I’ve done that through just testing. Nice to see the car voltage at all times. Both chargers work just fine although using an app to test the 2.41 seem to always charge slightly faster than the QC 3.0. the most I’ve seen was 1.6 amps to my phone through the 2.4. and around 1.4 or so with the QC 3.0. Not sure what’s going on there but they both work and have sufficient charge. I don’t think my old one ever got the ratings it claimed either. You can use Ampere for basic or Accubattery for everything you would ever want to know with your phone battery condition and charging and discharging. This is on Android.
