Hi all, didn't quite know where to post this one.

But I recently travelled in a mate's new Merc C class and noted that the pop up GPS/multi media screen in his car was not a touch screen.

Whilst I was impressed with the quality and size of the screen (aside from GPS which is nowhere near as good with graphics as the RNS510 in my car), I found that not having a touch screen made it very fiddly and unintuitive to use.

Now having been in a fair few Mercs, BMW and Audis lately, I have noticed that none of them seem to have touch screens. Even Lexus has reverted to a non-touch screen for their new RX350.

For me, the BEST thing about the RNS510 is that it is a very easy to use, intuitive, touch screen.

Hence my question: why haven't the other (supposedly superior) makers cottoned on?

Is it just me or is this one of the best kept secrets about the RNS510?
