Hi mates,
I tried to upgrade my Audio50 APS NTG1 headunit (european) firmware as MB's homepage said...
![Image]()
My problem is: the 1-3-8 button combination should start the update process but nothing happens...
MB's info:
"This Special Tool updates the software of the COMAND system."
and
"Update procedure
❯ Turn ignition on.
❯ Ensure that there is no disc in the head unit
drive.
❯ To start software update press 1, 3 and 8
at the same time.
❯ Insert service update disc.
❯ After confirming the new software version the
update will start automatically.
❯ After the update is completed, turn ignition off
and lock the car. Wait until instrument cluster
turns off."
Anyone can say my HU is NOT a Comand unit that's why it doesn't work or Audio50 APS has a different button combinations for firmware upgrade?
***remark: I've found the engineering menu but it doesn't contains any firmware upgrading parameter.
