Hi all

From the start very sorry for my english (I live in England but I'm Polish)

I hope someone can help me.

Here is my problem.

A few days ago I bought NAVIGATION RNS-E PU Led Media 2010. I got in my car, an older model RNS-E so the installation consisted of only the replacing of units and adequate adaptation.
Everything went OK and it worked without a problem.

After a few days I wanted to upgrade it to PL menu, I got from a friend right software and I have uploaded it to my new rns-e pu.

And everything was fine and dandy but the software was code SW200 and when I insert the maps from 2012 years where is sw220 everything was upgrade and again change to English.

On another forum a member has advised me:

In the older model RNS-E to change SW value need edit the txt file and there's probably the same so it's no philosophy
So I did.

In the software with PL menu of that have worked before without problem, I edited the txt file and changed the value of SW200 to SW250, then recorded on a CD and put it in drive.
After a moment started the update progress bar, came to end then the screen turned off , then switched on and showed this.
Check CD-ROM




After pulling the disc shows the message

Set Original CD-ROM





I read somewhere on the other forums that supposedly helps insert original DVD but not always, I have not tried it because I have only backups.

Removing the battery does not work, after re-connection the unit shows the same display.

There is no read-out via VAG-COM, which was possible before. The unit completely does not respond to any combination of button pushing.

Screen opens and closes, no problem.

Somebody, please help me.

Thank you very much!
