Hi all,
I am trying to install the above into an Audi A4 which is a canbus vehicle.
I got everything plugged in and it all looked to be working fine but after 2-3 minutes the unit always switches itself off. I have noticed the Canbus adapter always gets very hot as well just before the unit switches off.
Could I have connected something incorrectly for this behaviour to occur?
Thanks
Please be more specific.
Do you have ISO connectors?
The CanBus module should be allready wired to the comnector. It was not? If no, post the wiring diagram received (maybe you feed 12 V in a 5V input?....).
În order to get help post pictures and more info.
Hi. The fitting kit I have used is the following;

The Canbus adapter is plugged in via the attachment to the ISO cable.
Let me know if you need any pictures.
Thanks
I'm sure there is no easy way to find the problem.
I would do the following :
First make sure that all pins in all connectors are firmly in their place (see below the example).
Get correct pinout data for all connectors (Car connectors, HU, the adaptor kit and the CanBus module and also the pinout for the old stereo). When searching for the car connectors pinout make sure you find the correct one (year, model, audio system type, etc).
After having all the data you should search for any mismatch (power instead of data, different voltages, etc).
I recomend this beacuase I bumped in a similar problem with my car. I have a Mazda 6 and for the same model and year the car Hu connector differs for the Bose system version and the non Bose version, and the pinout of the adapter and Hu is not taking in consideration this posibility. Therefore I had to cut and reconnect some wires.
And one more thing : when I installed my Hu, some pins slipped out of their slots inside the connectors and my CanBus module was beep-ing constantly and the Hu was not starting at all. I had to use a very thin metal rod to push them back into position (with the connectors plugged in).
Thanks for your help. It turns out a Parrot bluetooth module was installed at some point and they have a good mess with the wiring and piggubacked onto the cars wiring. I am having to use that to power the unit now as it stops it turning off after 3 minutes. My next problem is that I don't have the steering controls option available in the settings menu. Any idea why?
If you are using CanBus you do not need that menu. The Hu has two 5V out and two inputs. If you have non CanBus Swc you need to take the 5V wire, pass it through your Swc and then to the Hu Swc input (the clasic controls usses resistors with different values for each button that atenuates the 5V from the Hu in different values for each button pressed and the Hu read that value through the swv input). So if your 5V wire and Swc input is not connected, you will not have the menu available. Once connected you must first go to factory menu and define each button (see the user manual))

Thanks. I've attached some pictures to show how the unit is connected to the Canbus adapter.
Key1 5V is connected to its equivalent going to the Canbus adapter.
Key2 5V is as above
GND is as above
Do I have it correct and am I just required to correctly map the buttons now?
Thanks
Still can't get this working.
Should I reset the headunit, update MCU and software or does it look like my wiring is wrong?
Thanks
No one can help you without being there. If you do no have the skills to do it yourself you should go to a electronics service.
As I said, you have to analyze all data. You must get all pin-outs and characteristics for your car.
You must know if your Swc is resistive or Can-bus.
With the car main stereo connectors pinout you will see what you have (resistive Swc, Can-bus wires, external amp signal, etc) and theirs place in the connector.
With the Hu pinout you will know what does the Hu can provide and what pins you should use.
And in your case you have a adapter in the middle, for witch you also need the pinout to make sure that everything is routed correctly.
After you have a clear diagram for your car you must check if fizicaly everything is as it should be.
How to get the pin-outs?
The Hu pinout should be on a sticker on the Hu itself.
For the car connectors you must first decode you vin and get info like year, options, version (usualy a more detailed pinout you find if you search the old stereo pin-out by it's exact make and model).
And for the adapter you must get it from the seller or from the Internet.
You said that before you, someone made modifications to wiring; this is one more reasons to get all informations and make yourself a clear wiring diagram for you to be able to start troubleshooting.
I realy wish I could help more but I can't, and there is nobody else that can give you help without being there to see (otherwise it would allready said sommething)
Best regards!
Just wondering. had any one try to mirror android head unit to another display. I brought HUDLY one of those head up display unit. in another word it can take hdmi input, most android head unit had video output rca turn out they just out put from the avin not the head unit itself. I was wondering i'm running android 7.1 on my head unit. can i connect usb mhl adapter to hdmi and my head unit display on my hudly or is there any way i can mirror my android head unit screen to my hudly either wire or wireless, prefer wire
If so, does anyone know which units support this? Is it all units? Does the CANBUS data get in via the OBD2 port? Does it still make it through with a bluetooth OBD2 connector?
Thanks!
Yes, I assume most units with canbus box will. There are canbus lines that feed directly to the radio connection socket.
My truck is a bit older so I didn't have any factory steering wheel controls.
With my previous pioneer units I was able to use an aftermarket steering wheel control that had a 3.5mm jack that plugged into every other radio I've had over the years. But my new PX6 unit doesn't have a 3.5mm jack....
Is there a specific wires on the Dasaita units that need to be connected to my 3.5mm wires? I can chop the end off if needed but I honestly have no idea what wires do what.
Am I wise to purchase different steering wheel controls?
For what it's worth, I was using this before with my other stereo https://axxessinterfaces.com/product/ASWC-1
What kind of " aftermarket steering wheel control" do you have ?
I think you can use it by connecting the "tip" of the jack to SWC (Key) of navigation, and the ground of the jack to the ground wire of navigation ...
Hi everyone,
I am trying to get my steering wheel controls working for my 2013 Volvo XC60. I purchased a P5 unit from Seicane and updated it with HAL9K Mod V4, which made the unit very stable with no issues. The only problem I am having; which I had before the update, is that I cannot get my steering wheel controls to work. The unit came with what looked like a CANBUS connector as part of the harness, but no box. Looking at my Volvo wiring diagram, I only have one wire for steering wheel control. When I connect that wire to KEY 1 or KEY 2 and try to program a button, it randomly ask me to select a function to assign a key.
Going through the wiring, the harness creates a bridge with the wiring harness for the information screen. It bridges off three connectors to the stereo harness and the connector that looks like its for a CANBUS BOX. The three wires are 2 CANBUS lines and a line that goes to the steering wheel remote. Since my vehicle is 2013, I think that i would need a CANBUS decoder box and that the unit should have come with one. Again, if its not needed, the only thing I can think of is bridging the lines from the CANBUS lines & steering wheel control wire that pull from the vehicle directly to the head units 2 CANBUS input lines and the KEY 1.
Sorry if this is confusing. Just seeing if there is something I am missing.
Please let me know if there are any details that I did not provide that would help solve the issue. Thank you.
