[HU_man]

You did just the 50% of the process, need to upload the fsc to the head unit using esys

I may not have fully understood how it works. What is the role of the bin file generated by HUTool on the USB stick? I thought the bin file would automatically transfer the fsc to the central unit and automatically activate carplay in a single step ??


I'm sorry for my ignorance I'm a beginner and I'm trying to understand how it works

With HU2.6 the bin file only clear old FSC in your HU. Thats why your navigation become grey/not active.
You must import FSC manually by Esys.
Drop me a PM if you need help.

HUTool 2.6 working very well, except it cant automatically install FSC by USB
