Thankyou. Was giving to give you a week of using it then check in. 
That document says it's for MY11 to MY13. Are the instructions the same for MY16 or any RNS850?V911406 RNS 850 Radio Software Update (11-13) Touareg (nhtsa.gov)
Page 4, second image from the top. This PDF is about firmware update, but it's the same way with the maps.
You activate Engineering Mode, then need to choose Update, then SD Card as a source, then there's confirming version window and after that You choose upload method; there are two available - standard (red circled) or user defined. The standard one should work, the RNS system checks itself which of the database file is newer and uploads only the fresh ones. It does it by comparing their versions.
Don't use Green Menu! Deleting whole partition of Your navi database isn't a wise move.
not yetWell @Steve_L , are you going to give it a go? I'd prefer to see another successful installation before I fiddle around with mine. I'm not confident with fiddling with my Treg's software guts.![]()
HiWell, You can go first and tell usShould be harmless.
I can also convert for You maps with 5.13.4 version for these regions:
- Hong Kong and Macau (HM);
- Bahrain, Kuwait, Oman, Qatar, Saudi Arabia and United Arab Emirates (ME and ME2);
- Botswana, Lesotho, Mozambique, Namibia, South Africa and Swaziland (SA);
- Malaysia, Brunei and Singapore (SM).
Cheers
Thanks, there is no hurry.I can make them... wait a bit.
So I've made this maps and sent them to @jatan231. If everything will work I'll post You up. If it fails as well![]()
