The C350 does, at least, offer full seven-digit postcode recognition and, once you're driving, Mio's old mapping engine does a good job of directing you to your destination. I've always liked its auto zoom feature, and still do: as you approach a turning, the point of view zooms right up and out, showing the junction from an overhead perspective, complete with animated arrows indicating the direction of travel. Other sat-navs do this, but none have ever done it as well as the Mio sat-navs did.
Adding waypoints to routes is simple enough, too, the map browsing mode responsive and there are some nice extra touches: click the power button on the top right and the C350 brings up the route info; click it again and text details of your route appear. A menu button on the front takes you quickly back to the device's root menu, where phone calls can be made and Bluetooth settings managed.
Elsewhere it works as well as previous budget Mio devices did: route choices seem largely sensible, long complicated routes are calculated swiftly and routes recalculated without delay when you stray off route.
It also acquires satellites swiftly and holds onto them no matter what. There are some surprising inclusions for a budget sat-nav, too. Just as the £100 Navigon 2100 did last week, the Binatone Carrera C350 combines UK and Ireland maps with Bluetooth hands free capabilities and preinstalled speed camera warnings.
