Saw the mods/hacks for the F and X series to display the posted speed limits and current speed. I have a X910bt but I can't stand the boot time, so I'm swapping for a z120. Just wondered if it is possible to do the speed sign hack with the z. Also, I saw the video blog from soundman about the competition (race) to get the Android OS installed on an AVIC. Apparently he was under the impression that you can get to the Windows (CE?) screen, can I do this? I thought this was a proprietary OS. Sorry if this is a multi-discussion thread. Primary discussion = posted speed limit signs. I NEED THAT cuz Garmin has it.. and i don't want my 1000000 dollar head unit to be beat by some lowly radioshack handheld gps haha.

No.
