I'll try to answer some of the questions, but note carefully which answers are 'guesses' and which are 'fact'.
1) Double Xenon Lights - The Touareg is a newer vehicle than the Phaeton. The lights in the Touareg are actually a bit of a hybrid lighting unit: The outboard light is a 'bi-xenon', meaning, it has a shutter in it that moves when the driver selects high beam, so there is an instantaneous switchover from low beam pattern light focusing to high beam light focusing. The inboard halogen light, which has a projector type lens, will illuminate when high beams are selected on (if the truck has been configured that way, using a scan tool), however, the inboard light is actually a supplemental high beam light, not the primary high beam light. The primary high beam light is the outboard one, with the shutter in the 'high' position. (All facts.) The European Phaetons that are ordered with double xenon lights (meaning, two xenon projectors on each side) have two 'single' xenons, the outboard provides a low beam pattern, and the inboard provides a high beam pattern. North American certification requirements probably don't permit the slight time lag required for ignition of the inboard xenon lamp when the high beams are selected on. (Educated guess.)
2) Radio Data Service North American Phaetons support static RDS (display of up to 8 characters that identify the station), but the ability to display dynamic RDS - the text that changes and shows the song lyrics, etc. - is not enabled on North American Phaetons. See this post for more information: RDS Radio Text Function. Read between the lines - there are some things I can't put in writing, if you get my drift. (All facts.) I am more than surprised that VW of NA has chosen to enable dynamic RDS on the Touaregs. I wonder if this was an oversight, or a change of heart?
3) On-board Electronic Owner Manual The North American Phaetons are fully capable of supporting the electronic owner manual function. I bought a navigation CD for Germany, stuffed it in my Phaeton, and the electronic owner manual function worked perfectly. See this post: Electronic Owner Manual works on North American Phaetons. The only reason the function does not work on North American Phaetons is that the navigation CD's for North America do not contain the required HTML files that comprise the owner manual. These exist in English to serve the UK market. (All facts, now the speculation follows.) My guess is that VW of NA chose not to support this feature for one of two reasons: Either the lawyers killed the idea, because they were worried about driver distraction, or, the computer industry has not yet invented a form of storage media large enough to contain all the asinine warnings that they wanted to add to the quite straightforward and factual European English language electronic owner manual. FYI, the paper (printed) owner manual in North America weighs more than twice what the European one weighs.
Judging from what PhaetonChix posted above about the 2005 models, it appears that we will never get this feature - at least, not from VW. But... one of our forum members, who has great skill in the computer industry, is currently in possession of my German CD, with the owner manual files, and is working on a project to combine these files with a North American navigation CD, to see if we can have this feature. Stay tuned...
