+1 on the update (X920BT unit) - it works.. Had a problem with the "INVALID SD CARD" issue though during the update (even though it was formatted FAT32). I had a 8 GB SDHC card, finally got it working by Reformatted the card using GUIFORMAT,EXE (using 16384 allocation size) and made sure QUICK FORMAT was disabled (not checked). I then extracted the files using 7-ZIP to a directory FIRST on my computer (made sure there weren't improper nesting of UPDATE, and FIRMWARE folders). This resulted in a /FIRMWARE /UPDATE CARDINFO.cif I then copied those files to the root of the rec

Hmmm, wasn't able to to the System uCom write but the APP VERSION is 5.1 on my setup. So I guess the first part of it did work before the uCom screen came up.

Was able to update my X920BT to the 2013 maps (5.0 firmware, and 3.32 BT firmware) but has anybody been able to update the X920BT to firmware 5.1? I wrote the contents of the file AVIC-X940BT_FW-Update-v5.100.zip to the a FAT32 formatted Micro SD card and the unit reboots to the UCOM screen just fine. When I select and chose "System uCom Write", i'm unable to continue because the next screen just shows [ --------- ] on the SD card instead of 8.05 (the uCom has 8.01). Seems as if the updater is checking to see if I have a X940 (and looking at a different folder).
