Hi esziszi,

Thanks for your detailled response.

My car is old (2004) and original stereo installation is quite complex... First problem, It's an all integrated device, including A/C control that cannot be separated from the stereo.

Some adaptation kit exists, but they are expensive (as PX6 Android unit) and provided A/C controls are not reliable, so I don't want to remove the genuine A/C controller.

In adds, I've a "premium" audio system, that have a good sound, but the speaker wiring is quite special. Audio amplifier include filters, so medium & tweeter wiring are separated, and I've an addtionnal amplifier with a subwoofer in the boot.

The previous owner installed an XCarLink to play MP3s. I'm satisfied for 2 years, it has some advantages (steering wheel commands via the original station, good sound) but also many disadvantages: it simulates a CD charger, so we must name the directories CD01, CD02 ... and I am limited to CD12 maxi, no display of TAG mp3 (not practical to find the title of a song), no bluetooth because it is the basic version ... And I need to use my phone for Waze and other applications. And it's not quite simple to find a good place for the phone in a car, It slips from its place while cornering, etc...

So the solution is to install the Dasaita PX6 as the Xcarlink. Use all functionnalities from the Android Unit except amplifier, and wire it through RCA to original stereo installation. I've alreday test it with another old stereo unit, it works but I need to do a quite special wiring. Here is the Honda CD charger Pinout:

As you can see, there is some additionnal specific signals like I2C. This communication bus is necessary to allow stereo unit to play sound from CDin. If the unit don't see anything on the I2C bus, it switches automatically to the radio... that's why I need to kept my Xcarlink or use this kind of device to emulate a charger and accept signal on CDin.

In add, commands from steering wheel are translated into command on I2C for CD charger. So not sure I can use is except if I can take steering wheel input directly on original stereo input. At least volume control will available with the car amplifier.

As you can see, I'm far away a "Plug & Play" installation.

Thanks for the tip, I'll try it.

I've Already install an aftermarket rear camera on my car. Camera is powered from reverse light, as you explain. But my current system (monitor is integrated into the rear view mirror) doesn't need and additionnal cable, it's switch monitor on when it detects a video signal. So that means I'll have to pull an extra cable... Not hard to do, but very long if you make it properly on a 5 meter long car...

So I'll not connect it.

As explain previously, tracks commands will are currently sent by I2C bus on CD charger plug. I need to find original steering wheel entry and derived it to the Dasaita.

I don't have any ISO connector, that's why I choose universal wiring with my Dasaita. I'll make wiring properly, I'm used to this kind of work.

I never listening radio, and I'll use my original equipement if I need it.

I'll root an USB cable to the glove box where I'll connect my smartphone. It will be useful if the wifi & bluetooth connection with the smartphone was activated when I plug the phone into the USB port.
