Hi all. Simple question. I just had a go with the tomTom 300 to navigate my way over a few hour journey in Yorkshire and find it quite good but i've had no experience of Audi's own RNS-E Sat Nav Plus system. For those who know - regardless of cost which is deemed better? Consider: - Reliability - Ease of use - Visual appearance Sorry for posting twice in 2 forums - just trying to get a wider variety of responses. Cheers, Mike.
