Based on your reviews it looks like the Ca-Fi 621000 is the clear winner by far. The work-around for the offline GPS is not too bad and anybody considering a CarPC (which is what an android HU is) should be ready to have to troubleshoot little odd things that don't seem to work exactly how they expect. The fact that the hardware is better in the Ca-Fi is the key here as software can always be updated. But you're stuck with the hardware.

You've used both personally, so your opinion should carry more weight than my purely academic viewpoint. But Reading your review/comparison sways me far more toward the Ca-Fi. I'm curious about the pricing on that one as that could be a big factor as well.
