Who has the most recent firmware for the rns850? I need the download
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.
Sorry I don't. I have EU if you would like to recover the situation but at the end you'll need a NA.You wouldn't happen to have an NA images for the RNS850 lying around.
RS232 is not OK. You will blow the RNS. You need a TTL serial cable 3V like the one in the doc.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??
