Hello all,
for people who, like me, bought a car with a F10BT not updated (Firware 1.000), here are the step I had to do to upgrade to 2017 maps version.
Notice that I have made lots of trying so, I'm not totally sure to remember all the actions have done but sharing my experience could help someone to win some hours...
The difficulty I had to upgrade is due to the hard work to find valid link for all firmware versions needed.
Step 1 :
Download Firmware Z110BT 1.001.
