Update...I check the fuses and disconnected the ground for 10 minutes. The DVD player will still eject a DVD but everything else is dead as far as the infotainment.Hi all, I tried to update my unit and it restarted a couple times and now the screen won't come on at all. I tried the five finger reset and it doesn't do anything. I left a battery tender plugged in during the update and the battery is fine but it seems my rns850 is bricked. I looked through the forums but can't find what step to take next, any advice? It seems i might be screwed, I'll keep googling but will take any advice you have.
Your post was somewhat better than the rest I have been ready. My 2011 also has 0170 version. Im scared to death to buy something from the internet and screw my wifes car up. Can you share with me the software you purchased and installed. Any other info would be appreciated.Well I have a feel good story, thanks to this forum!!!
I just bought a 2011 Touareg. Love it, except when I tried to pair my phone up it wouldn't work. My phone didn't see the car, the car was full of old bluetooth profiles. I tried to delete the old profiles and it came back saying it couldn't delete them. I downloaded the software update but just couldn't pull the trigger on modifying something on my new car with something I downloaded off the internet. So I went into the dealer, they tried a few things then had me leave it there so they could run diagnostics on it. They came back and said there was a faulty module 5F....just under $1000 to repair. Ouch. They also said that VW had no software update for my vehicle, despite the present version being 170. I thought if it needs to be replaced, I had nothing to lose by trying the update. The service guys agreed. I came home, did the update and...success! All the old profiles are gone and bluetooth works perfect, both with the phone and audio.
I'm a happy man! Thanks to everyone here that made this possible!
Just leave the 0170 version and not update? Can I upgrade the Nav firmware with this low version? I don't understand why VW makes this so hard and so expensive. Love the damn car though.I updated our 2011 from 0170 to v711, if you are not having any problems I would suggest you stay on original Software.
Why you ask ? Because I was having zero issues with original software and now it takes over a minute sometimes for unit to fully boot up, more annoying than anything else.
I may be able to help with v711, PM me if interested.
You need the latest software to work with the latest maps apple is the same way with there iOS updates that is just how software works. Android was also like this for the longest time if you want the latest phone app you would have to update the os. This all is normal.Just leave the 0170 version and not update?
