Hi to all.
I'm owner of a used 2009 e91, it has cic equipped by factory, but is an old version one telnet only and don't allow for usb update.
At the moment I have 2008-2 premium maps , first owner of this car was not a tech guy and did not care about it.
I wish to update to latest maps but 3xdvd are 2020-2, and more recent updates are only through usb drives.
I've been at dealer to ask for update the cic, but he told me he will not update because is a dangerous operation (unit in footwell could be bricked, it happened on a car last week he said).
He told me that eventually replacing the bricked unit will cost me about 500 euros.
Before landing to this forum I've buit an enet cable to access the cic and I was hoping to ftp it but I discovered it only allows me to telnet.
While telnetting the cic I saw that if I insert a map dvd it creates a symlink folder "/src" into root pointed to "/fs/cd0" and I thought to modify symlink to point "/fs/usb0" which is my thumbdrive in glove box.
Obviously replacing the simlink with ln -s (or -sf) did not work, as filesystem is read only.
Reading through some forum I've seen is possible to rw mount filesystem using :
"mnt_hd.sh -w" or "mount -o remount rw /mnt/efs_ro/" (this one to make flash rw) or "mount -uw /mnt/xxx" .
I didn't tested first statement, I've tried second and third ones using / as path , or trying to remount /fs/cd0 as rw but no joy, I wasn't able to modify symlink.
I'd like to find a safe way to replace symlink "/src" or it's content only to start a regular map update via usb thumbdrive without have to risk my cic or any other unit inside my car.
I'm not experienced in qnx but a litlle bit experienced in some linux distro, and any hint or help is really apprecciated.
Thank you for any help you could give me and forgive my not excellent english.
Regards J.
