Just picked my new Tiguan at the weekend and still playing with the toys. Noticed this thread so thought I'd do some research. The Owner's Manual implies that you can use a VW internet site (Volkswagen NAV Companion) to find locations, place them on an SD card andload them up in the RNS510, but it's not very specific about the site to use.
I did find the German version of the site at
http://www.volkswagen.de/de/navigation/adressnavigation.html (I searched in vain for an English version - let me know if you find one). It appears that you can create vCards (a small file with location information in it) from this site and place them on an SD card for uploading into the RNS510. It's dead easy and quite useful. Don't be put off by the fact that the site is in German as it's really easy to use...
- Go to the url as above
- In the 'Interesse' box enter an address such as '123 Green Lane'
- In the 'Ort' box enter a town such as 'Littleborough'
- Click on the 'Suche Starten' button and the map will show a point corresponding to the address
- Click on the 'Fur Adress-Navigation speichern' button on the map or the listing on the left
- This will create a file on your PC called '123 Green Lane....vcf' (might be in your Downloads folder)
- Insert your SD card into your PC and create a folder called 'Destinations' at the root of the card (i.e. not in any other folder)
- Copy this file to your SD card into the 'Destinations' folder and eject it from your PC
- Place the SD card in your RNS510 and choose Navigation/New destination
- You may have to wait for the SD card to become available as the unit may take time to recognise it.
- If all has gone well you should be able to select the destination or you can import it as a stored location.
I've tried a variety of destinations on the web-site as follows (some details of what I was trying obscured for internet use)...
Interesse = 123 Green Lane, Ort = Littleborough (Example of address)
Interesse = D12 3EF, Ort = Deetown (Example of postcode)
Interesse = Currys, Ort = Wednesbury (Example of business)
Interesse = Port, Ort = Dover (Example of UK POI)
Interesse = Port, Ort = Calais (Example of Euro POI)
I'm sure there are other combinations that would yield interesting results. It seems to work really well. There is also a POI (Points Of Interest) loader function but my German isn't good enough! Feel free to try it though.
So, Volkswagen UK, how about asking your German counterparts to provide an English translation on the site, or hosting a version of it on the UK site?
