Factory fitted navigation tends to be short on features compared with the latest aftermarket kits. Such is our usual refrain at this stage of our car tech reviews. We were not, therefore, expecting the C5's sat-nav to blow us away with high-tech traffic analysis, online services or anything actually innovative. Nevertheless, Citroën's NaviDrive system still pulled off the impressive trick of undershooting our modest expectations.
First up, support for postcode input is conspicuous by its absence. Destination input options are restricted to full street and town address or grid co-ordinates. The lack of touch-screen input hardly helps, either. Then there's the rough and ready map rendering. Whether viewed in 2D top down or pseudo 3D, it ain't pretty.
Consequently, address input is laboriously achieved via the small scroll wheel on the main console. The slicker-operating right-hand scroller on the steering wheel can also be used (the left is reserved for controlling the instrument cluster), but in practice it's every bit as fiddly.
Having said all that, once on the move, NaviDrive works well enough. It does at least include RDS-TMC traffic data giving you a modicum of awareness of traffic conditions. It's also a hard drive based rig programmed with European-wide maps which is always preferable in terms of both performance and ease of updates to the DVD-based alternatives. Likewise, in our experience, the voice guidance notes are timely and accurate. What's more, with the secondary display in the instrument cluster providing an alternative to the main display, you needn't gaze too often at the ghastly map rendering.
