Hi Guys Just an update. I managed to get access to a guy with VCDS. Successfully enabled the " secret menu" ( the one that's accessed by pressing and holding. "Set up" for 30 sec) Then selected the option to down grade the firmware and then successfully installed firmware version 4120. All went well and I now have radio text and have noticed other interface improvements. Thanks for all the help and guidance. Ps (slightly off topic) while I was using the VCDS I carried out a number of other mods - now have the fog lights rather than the xeons as my coming home lights for example ) Regards

Hi KB I'm not sure what radio text is - so I probably don't have it! I'm in Dublin , Ireland, so a trip to Hereford is not a realistic option. I have a standard OBDIi reader - and it's find for basic fault codes but I will link up with someone with access to a VCDS. As a matter of interest where would one acquire a suitable low cost VCDS ( both hardware and soft ware) that would solve my problems? I'm sure there are cutting edge main dealer ones produced by VAG- but. Are there are likely to be fully functional after market ones too?

Thanks Dave, that's very clear. I don't currently have any secret menus - so a hook up to VCDS to follow the route described by you might be the best way forward. Thanks for the help.

Hi KB I have the part number which I read off the device , which I extracted for the sole purpose of getting this info. I also read off from the sticker, the firmware version. So I got advice as to the appropriate firmware that I needed based on this data. But my device won't let me upgrade,( it thinks I'm trying to downgrade) Perhaps because the actual firmware in the device is not what is reported on the sticker? In any event one solution for me is to electronically determine what the firmware actually is. Which I could do if I had the secret menu - which I don't. The other solution is , as you suggest is to get to someone ( preferable not a main dealer) with VCDS to tell me what I have ( and if he can also at the same time enable the secret menu then all the better) I've no great urgency in upgrading the firmware - I'm just an tinkerer by nature and want to see what's possible. I only recently acquired the car ( and very nice it is too!) and my initial project was to get the latest maps - I now have v10 and am happy ( for now!... I'm told V11 is appearing currently ....) Great site by the way... Regards E

Thanks Phil Unfortunately I'm in a catch 22 situation , I can't access the secret menu with my current firmware - after I change the firmware I'll be able to access the secret menu , but until I access the secret menu I can't change the firmware. Joseph Heller would have been pleased with my difficulties! Can anyone else give guidance on how I might change my firmware - it is looking like a main dealer visit is the best option at this stage - but I'm not inclined to pay main dealer serviced charges!

Thanks Phil - one of the reason I want to change my firmware is to have access to the secret menu ( ie the "long" press on the setup button) How did you manage to overcome your difficulties ?

I've no problem loading up the maps as I've access to an official copy of version 10 of the maps. I downloaded and burned a cd of "RNS510 firmware 4120 modified for Europe" ( thanks to the good people at rnsfirmware dot com) The version I have is "....with 70/25/5 partition ratios, secret menus and VIM enabled" according to the blurb. When I tried to upgrade my system I got a message saying.."..you can't down grade your soft ware.." This implies to me that my firmware may be to a higher version than indicated on the case.... But in the absence of access to the "secret menu" I've no way of knowing. Looks like I may need to visit a dealer with a vehicle specific OBDII ( or whatever it's called) to read it for me? Any other ideas? Incidentally if any members in the Dublin area would like help upgrading their maps to v10 I'd be happy to help... Regards..

Thank you very much for a speedy response I'll try that and see how I get on. Do I need a non factory firmware to avoid having to recode?

Hi guys Ive just read this thread from top to bottom and cant find an answer that matches my specific question: data from label on the case of the unit; 3T0 035 680 A HW 71 SW 2854 date on unit 26 06 2013 in a 2010 superb Ive just updated the maps to V10 and all is well. I cant access the "secret menu" so cant verify that the SW in the machine is the same as on the label. Question what is the appropriate firmware upgrade for me? thank you in anticipation.
