SL55/63/65/R230 AMG: Has anyone upgraded their head units to the Android Chinese Models?
connector or did you use the short cable one)
I assume end marked 1 and 2 are the front since connector 1 is the same as canbus and connector 2 fits into new head unit.
on the internet. My connector is the same but wire colors are different so I have no clue as of yet.
I am not doing a new amp for now want it working here is a pic of the connector
As I wrote before the sound with my set up is in the same level as the original Bose set up and it looks original, and it is nice to have some buttons and knobs to control the unit easy.

There is a problem to address that seems to have gone without mention. The factory amplifier has 7 channels of amplification to drive 8 speakers. I presume a Chinese head unit has 4 channels...

had same issue it also took a few minutes to power even with those and would shut down after a few unites. Once all wires are connected it’s works except for reception of radio

As soon as the station gets week it start to search, can’t find anything in the settings to prevent it. Worst for me is that 107.3 is almost impossible to listen to, one of the popular frequencies where I live. I know that US freqency steps is different from Europe, can it be so there is a EU FM tuner instead of US FM tuner, I don’t know if that is a SW thing these days.
I have conncted the original antenna connector to the HU using the antenna adapter that came with the kit.
What I find more disturbing is the difficulty to read the display, the backlight is very week during daylight, night’s no problem.
The twin USB can I only use for charging the phone, there is no acces to the stored music on the phone, neither can’t I play music from a USB memory.
Mini SD with music on installed in the DVD SD slot works perfect.
Internet radio works greate and that is the most important thing for me.
I must sort out the backlight issue, any Ideas out there?
