BMW's new Real Time Traffic Information navigation system

BMW’s new Real Time Traffic Information navigation system is a problem-solving Sig Alert. Where other auto manufacturers’ navigation systems rely on preprogrammed disks with GPS updates, RTTI constantly gathers and streams data from FM radio, roadway sensors, video monitors and local traffic monitoring centers. And, when the resulting congestion calculations suggest more than a five-minute delay, BMW’s navigation system takes it a step further by proposing alternate routes.

While not proprietary, BMW’s RTTI is clearly ahead of the competition. (Audi won’t release its own version until spring 2009.)

It’s available this month in select 2007 BMW models and, no, older navigation systems aren’t available for RTTI retrofits.

However, BMW promises no activation fees or recurring monthly charges for at least four years.
