Hi!
I confirm that this will bring your avic back to life
1 - Service mode -> format with 2.009 - WINCEIMG
2 - Install Ver 2.009
3 - Enter WINCE
4 - Update with SDMLC_NN746_EW_sn00aa0f
5- WINCEIMG + WINCEIMG.CKS from version 3.021 and do a "Upgrade from SD/USB (formated)" in service mode
6 - Copy / paste the files from "My Flash Disk"
Still minor bugs, but I´ll try to fix them...
