Yes, indeed the bar in black color on top that shows the turns and the direction is quite in the way, it's inconvenient,
I have marked the bar with a yellow border, for better visibility.
There should be zoom, move and hide options.
Maybe we should reach out to the Waze developers.
Say hello to all of us Weizers.
Excuse my google english.

Hello. whenever I have the cell phone's Bluetooth connected to the radio, and I listen to a song or video (YouTube/Spotify/chrome) on the cell phone, it always stops, just not if the radio's bluetooth sound application is open. what options do i have to change, so as not to stop the sound of the cell phone when i do not have the sm bluetooth radio application open?
You tried to update the firmware already? I know there was an audio focus bug.

Hi, I have installed a reversing camera which works ok, but the problem is that the image does not appear until maybe 30 seconds after putting the keys in contact. The supplier tells me that this is normal, could anyone tell me if there is a solution? Thanks
Usually the image should be there with a delay of ~1 second after you switched to reverse gear.
But we need further details how your reverse camera is connected to power supply.
Hi, the camera is connected to the rear cigarette lighter, the red cable next to the RCA connector ( head unit end) is not connected. The camera is connected to the RCA cable via a 4 pin connector. The head unit is configured not to sleep, if that is relevant? Thanks
Do you only have the delay if you're in reverse gear during boot of the system? Or every time you want to drive back?
Where do you get the BACK signal? From reverse light?
The camera image should be shown even if Android is in boot process. In this state you should see the picture without guide lines because those are painted by Android on top of the image.
Hi, the back signal comes from the canbus. I have just installed the camera, tomorrow I will check if the problem also exists when I have been driving a bit, then test if image appears when I select reverse
When the head unit is already booted, then the image from the reverse camera appears about 2 seconds after selecting reverse.
When the unit is starting to boot, then the image comes about 10 - 15 seconds after selecting reverse. In this time the head unit is not yet fully booted
Sounds like reverse information from canbus gets interpreted by an Android module. Does your can box has an additional reverse output you could connect with the reverse wire of your head unit?
There is a trigger wire from the car to the canbus, which informs the head unit to switch to reverse camera display. I could connect this wire to the extra wire which runs the length of the RCA cable if you think that might help? Sorry, but not sure what you mean by the reverse wire of the head unit?
The head unit should have a loose wire labeled with "REV" or "REVERSE". Is it connected to the can box?

Use an external mic and deconnect the internal one:

Could be a good idea to check if ACC and B+ aren't swapped.
I think I've seen somewhere in the 8878 menu an AC setting. Maybe it helps to turn it off. Don't know if it was in Others or Menu Icons section.
Another approach would be to disable the AC activity via an ADB command so Android blocks its execution.
The head unit has an ILL pin. If you turn on your cars lights the ILL provides a 12V+ signal. Sure, you could also connect ACC from OEM radio connector to ILL input of the head unit to always turn on the button background illumination.
Absolutely correct. But maybe your cars SWC is realized by a resistance matrix which gets exposed to the OEM radio connector. In this case you can bypass the can box, use the KEY1/KEY2 pins of your head unit and so the learning function.
You could also check if the not recognized buttons get logged (logcat reader). In this case you could use AppSwitcher app for this buttons.

In 8878 menu, you have a setting for AC type, or something like this. You have one fullscreen option (that I hate too), and two aditional bars on bottom of display; choose ac type (or something like this) 2.1 -

AppSwitcher - smart SWC launcher (for Junsun and similar devices) incl. autostart
AppSwitcher SWC (Steering Wheel Control) app...

As soon as there are +12 V on the reverse wire your should see the rear view camera app with a black screen (if rear view camera signal is not connected).

Not a V1 pro with an old android version.2
They told me the same thing and it's not true, I can do tethering by bt. I copy and paste from a post that I put pages back, I hope it helps you.
My headunit is a kapud mtk8257, but it is very similar to Junsun V1 Pro.
In 90% of the cases, if before connecting the bluetooth on the mobile I am already allowing tethering (phone) automatically the headunit picks up the internet from the mobile.
But other times I have to force it: the button is "hidden", once connected to the phone, go into settings, click on the magnifying glass/search engine, look for "previously connected devices", click on your phone, and you will see that one of the buttons is "allow internet connection" or something similar.
PS: I have the radio in Spanish language, but the name of the menus should be like this, or similar.2
Today I applied the Firmware Stock update procedure. The procedure was successful and the tablet works ok. It remains to put it back in the car and see how it behaves in tests. This was possible for the two users who thank them once again: djborsi and TorstenH. I removed the tablet from the car and made the connections to be able to work with a + 12V DC / 220v power supply. For those who want to power it separately from the car, I put some pictures after the procedure and a wiring diagram. I made a video with the FW update procedure. Because I noticed that the tablet heats up a lot, I mounted a 12V / DC fan, It has the size 70X70mm. and thickness 15 mm. It was from an old CPU cooler. It is fastened at the back with 4 screws as seen in the photo. I put a 40 Ohm series resistor. to reduce speed and noise. I hope that what I posted here will bring a little help to those interested.
