So everything is OK. Pushed the cover in it's place, it's a perfect fit.
Now to the info panel.
At this I realized I needed to remove the whole lower trim to make a good job.
So the lower central piece should come off. Not difficult if you have already removed both side panels.
For the glove box, it's easy (see the picture above where I've routed one of the USB cables). You'll have to push gently from one side, then from the other to get it loose. Then with the door wide open you'll get access to the screws of the back panel and one clip that you should undo by pushing its center. You might want or not to loose the clip that holds the airbag connection to the panel, it's easy do it from inside.
So with the side panels loose it's easy to access the clips of the center lower trim. There is one clip (top corner) on the steering side, and about three on the other side. There's also a screw (bottom corner) on the steering side that shouldn't be there if you already removed the panel bellow the steering wheel (it hold both panels).
With the center panel out, I had access to the inside radio frame. And the back of the relocation panel fits perfectly there, see the picture (red is the main PCB connector, yellow is compass PCB connector).
But before that, I had to sort out where in hell the compass PCB should be placed.
The kit is provide with a plastic plate that will hold the original plastic case of the compass PCB, but the thing doesn't fit anywhere... At least I didn't found any obvious spot where it would fit naturally.
It's kind of weird... So as there were no instructions for this, I though the best place would be stuck to the back cover as the cable that connects it to the main PCB is quite short. The important here I think is that it should placed perpendicularly to the vehicle.
So with the help of some double sided tape I've sticked it to the back cover. Notice it is not perfectly aligned with the back, as there should be enough place for the main connector.
As it's shown in the above picture the main PCB attached to the relocation panel is placed outside the lower center console trim, and the back cover should go inside.
There are some metal clips (yellow) provided with the kit that although fit the sides of the relocation panel are not to be used here (I realized that after placing the panel). There meant to be used with the optional single din pocket that is also provided with the fitting kit (in case you don't have an info panel to relocate).
Although it's not very visible in the picture (red) there is an hole in each side which are there to hold two claws of the back cover. That's how the relocation panel is held in place from inside.
Problem is, mine didn't held in place. Beside that I wasn't confortable with the idea of the whole thing to be secured with two tiny claws from inside... So I solved the problem easily with a solder iron.
I made two holes on each side of the back cover.
And secured the thing with two zip ties (yellow, so anyone who tries to dismantle this will notice them).
Of course, it is not to forget to connect the compass board to the main PCB and connect this to the car's info panel connector to make a quick test, BEFORE tying the thing.
Important note: In my case, there was a capacitor on the main PCB that was in way. There is enough room to place the panel with the PCB in the center console, but press gently as this capacitor (red) will bend a little bit against the console.
Next with the info panel in its new place, I just needed to plug the grey connector (info panel) to the main PCB through the hole of the back cover. No problem with that, there is enough cable to do that easily. Then the center console goes to it's place, and next the same with the side panels.
And it's done!
Hope to review this wonder of head unit soon!
