Thank you wamba, yesterday evening i just found this fw database and successfully updated to 0253.
anyway, i don't know how to activate the SWaP codes, i am just old for that :D
yes, there is a lot of tutorials, but i thought that the patch is applicable for standard fw folder structure.
many thanks
today i will try to 0363, but don't know if it will work on indexB device.
update: no, 0363 does not work on my device...
i just want it for VOICE MENU NAV access for "CAR" menu, now i have to access only via Hybrid menu activation/deactivation... #sad
