OK guys... got my car phone working again..!!
Lets start saying that TCU was ok.
After a lot of investigation I found a damaged cable underneath my central console.
After I repaired it, the phone kept refusing to work, so I had to go for the next step and decided to have a look inside my eject box too.
There I found a little smd component damaged which I desoldered (looks like a 3 pin resistor or diode) and then wanted to give a try without it just to see if something chenged in behaviour of the whole phone and in a try to get some hints.
Surprisigly enough, it started working..! Phone recognized there was a sim inserted and in a few secs it was registered on the net.
Maybe the little smd was part of a voltege divider which is not critical... I dont really know what it was meant for, but all is working without it..!
If I found a schematics i might have given a try to discover what it was and replaced it.
During the next days I'll test the phone extensively and will come back to you with any news.
Anyway, at last, now we have a working phone to play with.
If you need some navcoder log or anything else, just ask..!
And last but not least, I want to thank you all for your help, and a special thank goes to Stringbag who offered to try before buy his TCU.
