On Episode 2 of InDigital, an IPTV show/video podcast, in a review of the Magellan Roadmate 800, they pitted a host with the Roadmate against a host with her own knowledge of Los Angeles in a 2 stop race to see who could get to the stops and back to the starting point first.  The segment starts around the 14 minute mark and is peppered with language I would think is common when driving in Los Angeles, definitely not kid friendly

Fun to watch and does mention the GPS unit for at least 30 seconds.
