I've been following all the discussions of converting the new 2011 RNS-E's from Euro to US software hoping to do the same to a cheap RNS-E 193G that I purchased on ebay from Europe for my 2008 A3.

After receiving my unit from Europe, I unplugged my old 193 (yes, the last version of the low res screen models), switched it with the new 193G and put in the supplied PIN code. High res happiness and only a 2 minute install...nice

One caveat is make sure your battery is plugged into a battery...
