[Android Head-Units] Phredeee:
I was told by Joying that one speaker BT is the way it is with all 5.1 Joying units. The 4.4 units may be different. Maybe it was just my unit but the audio quality was so bad that I could not understand callers. Streaming music (A2DP) was just fine but phone calls were awful. BTW steering wheel buttons did not work when streaming music from the phone.

The glue was surrounding the DVD bezel and in the slot. I worked on it a lot and was able to remove the goo to an acceptable point. However there was never any film on the bezel and it showed with spots and scratches.

Installation required modification of the OEM brackets as the holes on the Joying unit caused it to sit about 1/4" too far out from the dash. Joyings answer was to leave the screws out. :rolleyes:

My unit had great FM performance all around, I hardly ever listen to FM.

WiFi sensitivity and performance was good. I wish it could have been either BT or USB tethered to my phone. Changing the phone to support a mobile hot spot every time I got in the car was a pain. I was about to install Tasker when I shipped it back.

Auto muting in reverse was a nice touch as was color adjustment of the hardware LEDs.

The iGo software missed the mark with my location by over 1/2 a mile and failed a few other tests for accuracy as well. I was able to install Google maps and reassign the NAVI button.

The steering wheel buttons worked well for stock apps. Being able to program long press functions is a nice feature. The buttons did not always work with other apps and did not work my phone.

The clock displays 00 hours after midnight in 12 hour mode, should be 12 AM.

CPU speed is 1.6Ghz not 1.8Ghz as said in ad. The RAM does not come close to 16MB as marketed(yes, I know about the marketing and engineering differences in specing RAM)

The music app does not support playlists and the steering wheel buttons do not work with other apps that do.

There can be an audio conflict with added applications. Music, DVD etc do not stop audio from added apps and 2 sources play together.

Mode button cycle does not include A2DP

The DVR app does not autostart. I was using CaroO instead.

The unit sometimes responded very slow and at times simply locked up. A few times the volume locked at a high level with no way to quiet it. Power off didn't work either. The options were to wait or shut the car off.

No way to set the dim amount when headlights come on.

The keyboard needed to be replaced with a US Google one in order to get symbols.

These things may or may not matter to you. When you add them all up it was more than I was willing to accept. Joyings answer was to replace the unit with what I found out only after questioning them, was a 4.4 unit. When I found out that return shipping was $150+ to China for the 3.3kg box I decided not to risk it again on something they really could not describe beforehand. All I would get to my questions was "trust us..."

I purchased mine from Amazon US. But the return needed to go to China at my expense! https://smile.amazon.com/gp/product/B01IBBVUXA/ref=oh_aui_detailpage_o08_s00?ie=UTF8&psc=1

Not meant to slam or whine. Just to share my experience. I hope yours is better.
