The 7310 has an RDS-TMC receiver built into the car charger. This gives you free traffic updates in some European countries, but in the UK you need to buy a subscription, which costs £40 for a lifetime of service. Considering that TomTom’s similarly-priced GO 730 (the European map version of the GO 530) includes this in the basic cost, Navigon looks a little stingy.
During navigation, the usual array of Navigon map view enhancements is available, and they’re quite effective. Lane Assistance Pro goes well beyond the usual turning arrow, showing all the carriageways at a junction and precisely which ones to be in to stay on the correct route. Reality View Pro takes this one stage further, displaying a full-screen graphic resembling the junction in 3D along with a realistic representation of the road sign, although this is only available at the most important intersections.
The Navigon 7310 is packed with features. The headline 3D enhancements still feel like a work in progress, but that doesn’t stop this being a very functional sat-nav overall. At around £300, it’s also priced reasonably considering the full Western European mapping and specification, although the necessity of forking out for a subscription to activate RDS-TMC in the UK reduces this. But if you do want a comprehensively capable personal navigation device, TomTom’s GO 740 LIVE, the European map version of the GO 540 LIVE, remains our top recommendation, assuming you travel frequently enough to make the monthly subscription worthwhile.
