Initially announced during SEMA 2008 in November and soon to be demonstrated at CES 2009, Cobra has developed new GPS-enabled radar detectors which sport smaller packaging and promise higher levels of performance with the incorporation of their proprietary Aura camera database.
You can read more about them at the following:
Cobra XRS R10G, Cobra XRS R8, Cobra XRS 9960G, Cobra XRS 9955 GPS-Enabled Radar Detectors
If Cobra's radar performance continues to show improvement over their previous models, I would expect these new radar/gps detectors to potentially be compelling offerings worthy of some consideration.
