Hi everyone!

I read on forum that some guys had version 0170 and then updated to version 711. I'm interested on version 0170. Does anyone have it?

Unfortunately I do not. I would never go backwards in firmware though.

I think so ... in any case before to upgrade the map there is an automatic software compatibility check.
If it is not you will be not allowed to go on.

If you look inside the MAP SD you will find an excel file with a SW compatibility table.

I bought an update there: vag-technikhttp://i.ebayimg.com/00/ | eBay Stores
It cames on 3 sd card, Installed and very satisfied.
Ya I bought that for my 2011 2 years ago. I have a friends car that has an odd screen that his sister found on the green menu and now it is stuck on this failed update screen. The RNS850 was acting funny so she thought she would fix it while borrowing the car. She searched online and found something about the green menu and pushed an update button. But she did not have an update disc.

When the red screen appears the situation is bad. The shudtdown timeout shall be interrupted via terminal serial link to the DVD box.

See attached doc.

You wouldn't happen to have an NA images for the RNS850 lying around. lol. Oddly I have a RS232 communication cable that I use on my RNS510.

Is there software to use with the RNS850?? ie: eeprom reader/writer in a user friendly software??

Sorry I don't. I have EU if you would like to recover the situation but at the end you'll need a NA.

RS232 is not OK. You will blow the RNS. You need a TTL serial cable 3V like the one in the doc.
You just need putty serial software. Nothing else.

The cable I have is a USB to rs232 rl com port that I only use rx tx and ground to read the eeprom inside the rns510.
If it is USB to RS232 it is a risk. Look at the doc attached.
