Have internet-enabled personal navigation devices - like the Dash Express - failed to see significant adoption because their connection isn't fast enough? That seems far-fetched, but something has convinced dmedia to slap WiMAX into their latest PND, the G5W.
As well as a 5-inch wide-aspect touchscreen, FM transmitter and Bluetooth - oh, and GPS of course - the G5W has GPRS, EDGE and WiMAX connectivity. It's not entirely clear what you can do with the WiMAX, aside from real-time traffic updates. We'd assume there's some sort of browser on there, pushing the G5W into pseudo-MID territory.
The dmedia G5W is conspicuous by its absence on dmedia's site, though there's a 5-inch widescreen G5 PND listed. We've no idea whether this is a CES prototype, a shipping product (if so, we don't know where) or just a concept, nor whether it will ever be available in the US for either Sprint or Clear's WiMAX networks.
