S05 Q
How can I see the progress of a software update or
find out if it has completed?
0
A
During the software update, switch your car radio to the CDC source
(SRC button or CDC button); see the operating instructions of your car
radio. In CDC mode, the car radio's display shows the progress of the
software update. For further information on this see question S06.
Note:
The software update will still function correctly even if you cannot see
a progress indicator on your car radio. After the update has started,
wait approx. 5 minutes before you switch off the radio again and
unplug the USB stick.
S
The boot loader (which cannot be modified on the customer side)
contains software for displaying the software loading information on
the car radio's display via the CDC interface.
A second piece of software for controlling the CDC interface exists
parallel to this within the application software – this second piece of
software is updated on the customer side when the software download
is performed.
As a result, the following behavior can occur:
During the software download, there may be no progress indicator
visible on the radio's display or it may appear incomplete; during
subsequent operation though, the indicator will work better / more
completely / differently.
However, if a software download is subsequently performed again, the
previously described progress indicator will be visible again as a result
of the unchanged boot-loader software.
Furthermore, it is also possible that a USB stick will work with the
application software (also a newer version) but not with an older
version of the boot-loader software. To perform the software update,
please use another USB stick that the boot loader recognizes.
