Avis is showing off its new Where2 portable nav unit this week, a customized Garmin Nuvi 780
that will replace the StreetPilot-based units currently in Avis' arsenal. The software has been mildly reworked to offer routing to Avis rental return locations and the like, but we think the best part of the customization is the bezel. Come on, tell us that red isn't way better than Garmin's own gray? Look for the new units to be available -- by rental only, of course -- in March.
