I'm due to change my 1250GSA next year, and I think I'll be going for an RT. I had a test ride recently, and was very impressed. My concern though is with the nav system on the TFT and having to rely on the phone signal etc for the nav to work. Has anyone had any experience of using this system, and is it reliable? The other point that worries me is, what if the rules on using your data allowance abroad changes? We would then have to pay for data roaming, which used to be very expensive.
