RNS-315 or RNS-510

[andyoc]

Just trying to decide on a spec as my next Company Car.

I have just been told that it is no longer possible to specify the RNS-315 by various Lease Companies.

Is it worth the extra for the RNS-510? I think this removes the DAB option but I am not sure.

I have read that the RNS-510 can be a little slow to respond, sometimes a few second pause when entering destinations..?

Not sure if to save the money and stay with my TomTom - I like the idea of the touch screen, and the reversing camera but it is a serious amount of money. Is it possible to get Speed Cameras on the RNS-510?

Thanks very much for any advice...
