Wondefoo PX6 radio for Mazda CX5 2013 - #1: Installation issues

[@acefr8816]

For the Bose system, the USB port in the center armrest is not connected directly to the headunit but to a bluetooth module behind the glove box then to the headunit. When you replace the factory headunit, you lose the bluetooth module functionality along with the USB port in the center armrest. To make it work, you can disconnect the harness to the bluetooth module, locate the 4 wires for the USB port, and solder them to USB A plug then plug into your Android USB port. It is lots of work, so I just get an aftermarket dual USB port and replace the factory USB port in the center armrest. I need 2 USB ports and the single factory port won't be enough anyway.

Amazing Video I’m looking myself for aftermarket radio can decide yet

Hello. Thanks for the great review. Observed the similar issue on my unit as well. Moreover, I couldn't make steering wheel buttons to work either. What are the Canbus settings to activate them? Thank you for your answer in advance.

[@fonseca73]

If you have the CANBUS adapter, make sure the SW1/SW2 wires are NOT connected to the radio. The steering wheel should just work without any config via the CANBUS. Even the app to configure the steering wheel buttons should be completely empty, nothing to configure there as it's all auto-configured via CANBUS. After disconnecting those wires, reboot the car+radio (ignition off, open/close the driver's door, ignition on).

Hi i have kind of the same problem as you. rear camera works just not the rear speakers. After watching your video I found I don't need the RCA leads. my front speakers work in the doors only but cant get the rears to work.

[@hwkcl]

I just bought a similar unit for my Mazda 6, with the same harness and canbus box, and I'm assuming I'll have the same connection issues for my rear camera 🥲 (I don't have the Bosé audio system)

[@صوتزرياب]

I have such a radio, but the original rear camera does not work, do you have an idea why?

[@fonseca73]

You can connect it to the RCA video input, but then it won't switch automatically when you engage the reverse gear - you need to manually start the 'AVIN' app to see it. To have it work automatically, we need to connect the 'BACK' wire to the car so that the radio knows when the Reverse gear is on - this wire is disconnected on the wiring harness they provide :( I haven't done this yet, I need to find the pin on the CX5 connector which turns on when the Reverse is engaged.

Thank you, the problem has been resolved

[@TIM-random]

Do I need to buy a canbus harness or i could wire the steering wheel control directly to the head unit?

[@fonseca73]

The unit itself supports connecting 2 wires for the wheel controls instead of CANBUS. However, I'm not sure those wires exist on the car side, as the car is designed to use the CANBUS. Other things also require the CANBUS signaling (like night/day detection, parking sensors indicators, etc), so I would not skip on the adapter.

[@TIM-random]

Thank you for your reply. I'll be considering buying the canbus adapter.

Hello, i have the same unit but my problem is that i havent any song, every thing is ok, rear camera , and all buttons works but i don't have song in my car...can you help me?

[@thomasmargueron5281]

Is that possible to show me how did you connect all the cables please? Sorry for my english , but i don't know what can i do for having song in my car...😓

[@irfanodobasic6799]

And how to solve this problem with Bose. Sound is damn to loud on the level 2 or 3.

[@fonseca73]

Quick fix: go the the factory menu (password 126) and set the Attenuation to -12 or -15db. This works but leaves an audible noise hiss in the background, and sometimes cell phone interference can also be heard. Correct fix: The speakers must be connected to the non-amplified outputs of the radio, not the amplified ones. Unfortunately the supplied wire harness doesn't come with the correct plugs for that, and I couldn't find one for sale either (I ordered 3 different ones and all were the same). So I had to get some RCA plugs and solder the wires myself to plug the car to the correct outputs - now the sound is perfect :) It's a bit of work, but not too much. I recommend getting a second wire harness that you can butcher to do this, so that you can always go back to the original one if things go wrong. Another missing wire on the supplied adapters is the Reverse/Parking signal wire that enables the reverse Camera view. I also added this wire, now the radio switches automatically to the camera when the reverse gear is engaged.

@@fonseca73hi! Thanks for this video. It’s really helping me out. I’ve already resolved a few issues. I would like to fix the sound issue. It’s not painfully loud but there is a low hiss / static sound and I assume it’s the same issue you outlined here. Do you have any idea which cable is the non amplified output? In order to get the sound working at all, I had to wire my AMP CONT wire to the ACC wire. So I do have sound, I just want to get rid of the hissing.

[@noumeg7782]

What about the command on the steering?

[@fonseca73]

That all worked fine without any configuration. If you have a CANBUS adapter, do NOT connect the SW1/SW2 wires. Read my comment below for more details

[@kenbalram334]

Hi,i bought this stereo and i had to ordered the canbus cable separately cause the originals don't match my car,would like to have more tips before installing, will it work?

[@fonseca73]

It should work, but it may need some tweaking. I eventually ordered a 2nd Canbus adapter+cables to see if it would fix the reverse camera but it didn't - I eventually fixed it by manually adding a missing wire to the cable harness. I think they sell these cable sets for the US market variants, and they're not 100% compatible with the EU variants. After the missing reverse camera wire, I made another modification to the wire harness to fix the audio volume/hissing issues - I connected the speakers to the RCA non-amplified outputs of the android unit. Now everything works :)

[@kenbalram334]

@fonseca73 I don't know much about wiring but now I plug up everything and they are 2 cables from the car that isn't plug in,there is no sound

[@fonseca73]

Not everything needs to be connected. If you have BOSE sound system, you need to connect the brown wire to the blue wire (AMP). If the volume is extremely loud, you'll need to adjust the gain in the factory menu (password 126), set it to -12db. Check video #4 in this series.

[@kenbalram334]

@fonseca73 my car doesn't have the same cables like yours
