Think that's probably a wise move. I was the same, really wanted the climate screen, but didn't want to pay for the premium phone package as
1) I have an Iphone (work supplied) and these are not rSAP compatible, therefore I wouldn't get any benefit other than charging - which incidentally I can do by plugging the iphone into the MDI port anyway and
2) The advanced phone package still doesn't give access to VW Car Net as VW UK are not offering this in the UK (despite it only being €100.00 in Germany. This would offer live traffic updates, google maps, google street view, Picture POI searches etc. Whilst non of this is actually needed in the car, at least if I had access to Car net, it would go towards justifying Premium phone package, but as it is, for me at least, it just isn't worth it.
