@Joec500 when you had the NM Automotive system running, did your reverse camera stay on then you started going forward until you hit a certain MPH, or did it go off as soon as you took the car out of reverse?
Just as a FYI, my Panamera has an OEM backup camera. When the PCM 3.1 was in place, the camera continued to show the rear view until the car reached a certain mph (about 9mph I think) and then reverted to the normal screen. Since fitting my Android HU, the camera shows the normal screen immediately upon disengaging reverse gear. I actually prefer that behaviour.
I installed my Erisin Head Unit (HU) yesterday. Pretty straightforward. I do want to look info an adapter to be able to use the OEM mic one day. But right now. I have two questions:
How do I change the temp to display in F vs C?
And most importantly, backup camera is not working. Here's what's going on:
When I put the car in R (manual) I get power out which turns on the camera's LED lights, but as for video, nothing happens. Specifically, the HU doesn't change. It's not like the HU changes to the backup cam screen and there's no picture, rather, the HU doesn't seem to do anything when I'm reverse (yet the backup camera power wire does switch on as I said)
Thoughts?
This is my backup camera.

It seems that the HU isn;t receiving the trigger signal which tells it to show the reverse camera screen. Is there a wire on your HU harness which is marked 'trigger'?

Ok I installed my Chstek unit replacing the Ersin unit. Took my a little longer as I reinstalled My PCM 3.1 to crank the volume up to 75% before powering it off ( I have the Bose amp), I missed this step on the Ersin install. *** Do no miss this step if you have the Bose configuration as I can testify it does make a difference. For those that are worried about not being OEM, it took me 20 minutes to convert back to OEM. My PCM 3.1 worked just like it did the day I uninstalled it. You do have to remember to move the optical connectors back if you have Bose.
I ordered my Chstek with the MOST box prewired. Ironically the MOST box they used was the same one I had ordered off of Amazon when I installed the Ersin HU. I did add 2 T-Taps for my back up camera, one for GND (tapped into MOST box GND lead) and one for PWR (which I tapped into the brown wire on the Android connector). Other than that it was just plug in all of the cables using existing or supplied adapters.
On the MOST box they have the Audio in labeled AUX RIN and AUX LIN, do NOT let this confuse you as they still have to be connected to AUDIO OUT L and AUDIO OUT R from the Chstek HU.
I used Blue painters tape to tape up the corners of the trim around the HU as the top of the Chstek unit is a much tighter fit. Worked great after installing the HU I was able to easily remove the tap and no damage to the trim!
Powered it on and it worked!
Things that made me happy:
- Dash board dimming worked without an update! Maybe they updated before sending my HU. It also fixed the gear and speed indicators which will still bright even after the Ersin fix.
- The radio display on the MFD works right out of the box, I know @ZedZed said it shouldn't but it does.
- The low volume with Siri and Carplay is no longer an issue! The volume of of texts and directions are no longer severely muted even using wireless Carplay ( I have not tried wired Carplay yet)
- Bigger screen and no more accidentally power it off when I am trying to adjust the volume. I really like the hard buttons but will probably remap them. Not sure what the CAR button even does
Things I want to improve:
- Not impressed with the base launcher it is not what I would call user friendly. I never updated the launcher on the Ersin and I am not an Android user, any recommendations on launchers and any guides to updating the launcher would be greatly appreciated!
- Change the hard button color to white from yellow/gold it is currently. I haven't found a setting for it yet, I went into the factory setting using 3368 and did not see anything? Any know what the code is to go into developer settings?
- Also it appears my SD button is broken, I think it was shipped broken I am going to contact Chstek and see if they will replace the unit. But is the SD button really needed?
Well done @mamick - and glad you used tape to protect the trim edges.

I haven't found a way to remap the hard buttons (yet!) and the seller says it isn't possible. NAV can be set your preferred (HU-installed) maps. CAR adjusts screen brightness (!).

Please see posts above re: launchers. Everyone will have their own preference. Mine is VIVID.

Not a button and not broken. It's a cover for an SD card slot that is not used on these units. Go figure! You're not the first to think it's broken!
Thanks for all the detail - really useful for others and we'll incorporate into the guide.
@AdamIsAdam On the temperature setting @ZedZed helped me with this months ago in post 1764
For all other sound settings, you will have to go into the Factory special menu. The code is 3368. Once there you will also see a setting called Out Temperature Fahrenheit - you may want to select this, although IDK what it does. I am guessing it allows you to set the Outside Temperature to read in F instead of the (default) C.
I would look at my HU menus but it is sitting here on my desk as I replaced it with the Chstek unit this morning.
I am sure you may get teh response but make sure your parking brake is not on as they will not allow the camera to work.
The camera (got form Amazon) I installed had three wires and an RCA video jack. I connected the GND to GND, the PWR to the Green CAM PWR lead from the HU and the trigger wire (from the camera) I did not connect to anything. I connected the RCA video jack from the camera to the the Green RCA jack labeled R CAM on the HU.
- The radio display on the MFD works right out of the box, I know @ZedZed said it shouldn't but it does.
I don't think I said it shouldn't - I said I don't see how it can since the cable that connects the PCM to the MFD is now not connected to anything at all So are you seeing the radio station frequency, name and content broadcast in the MFD now? If so, that is amazing (and unfathomable!_.

There's a section in the Guide about this.

It isn't a button - it's a cover for the SD card holder.

@ratt359 Thanks for the info, yeah the SD had me worried. I was trying to figure out how I broke it.
The tape trick was based on others talking about scratching the leather.
This forum is really informative and great way to learn. Have to keep up daily as there lots of posts! Which is great!
@ZedZed yes the radio display in the MFD works, it worked as follows with the Ersin unit, if you changed radio stations it would show the radio station but it would default to T0000. But ince it showed a radio station it would update as you changed displays.
But with the Chstek unit it works as soon as I power it one and if I switch stations it change sand updates, so no T0000 default display.
Just to clarify I have only tried FM radio stations.
For giggles I tried the Telephone display on the MFD and all it says is BT, oh well it was worth a shot.
If anyone is in the states and wants my Ersin HU with a prewired MOST box for BOSE (can be removed if not needed), $100 shipping included. Just PM me. HU works great and has all cables and has been updated with CANbus upgrade for dash dimming.
... and likewise if anyone in the UK would like an Erisin HU for non-BOSE, with the bright lights fix and some much more OEM style control ***** then please PM me!
