I checked the latest X940 manual and it said to update the firmware if `Ipod Settings' is not displayed in AV settings; http://www.pioneerelectronics.com/PUSA/Car/GPS-Navigation/AVIC-X940BT
I downloaded the latest firmware on a 32gb microSDHC formatted to fat32 and 16kb allocation. When it boots into testmode the firmware (ucom) on the microSD card is displayed as `--- ------' instead of the expected `8.05'. The current version was listed as `8.02'. Could this be more an issue that the X930 and X9310 cannot support the firmware update for a X940 even with the upgraded software to 6.0?
