Does anyone know how to do a hard reset on these? I want to restore it back to the way it was when i first bought it. My Voice Recognition isn't working and i want to try resetting it. I have tried reinstalling the software but it put the SD card in and it just boots normally. Thanks for any help.

Have you modified the software on the internal flash drive? If so, the only way to restore it is to install your backup over the top of the current data.

If not, holding the eject button and pushing reset will restore factory defaults.

Just a followup question.. Would the firmware update remain on the Headunit after a hard reset? Or would you have to re-update that, as well?

Thanks.
