@Elpibe I have the exact same problem with my 2015 Subaru audio system and posted it under a different thread some time ago. This pairing problem seems - at least in part - also be caused by the Subaru audio system and not only by UBtouch. I had no problems pairing my FP2 or N5 with audio systems in several rental cars from different companies (Nissan Micra, Hyundai Accent and Ford Mustang) with music player, contacts and phone calls mostly working (some funny behavior on the Nissan when accepting incoming calls). I will try htc_tatoo's command line solution.

@thilov . Thanks for posting this. Will confirm.

with the correct time. My time zone is GMT -4 (and so is the timezone of outlook from which I exported the file). Any idea where this shift may never comming from ?

Thanks for opening this thread. I tried to replicate this (copying the calendar file to ~/.local/shared/calendar/systems) and it worked, but all appointments were shifted by -4 hours. Interestingly, in the clock section of the noification bar, allevents are listed

@dobey Reformatting did the job. Thank you. Interestingly the name of the SD-card in the file manager is different from the one in the "External Drives " but works fine.

I have a similar problem on my FP2. When I start the phone, I am notified that a SIM card has been detected and I can see it in the "External Drives" as SS16G. However, I can not find it in the file manager as a media device or folder. It is listed in /dev/disk/by-id as mmsc-SS16G_0xf3c11129.
Any idea how to mount the SD card to be visible in the file manager ?

@grandpa

Why would UbPorts foundation with it's stated objective of respecting user privacy and open source software even remotely consider cooperating with the most intransparented IT-company in the world, bound to the regulations of an authoritarian anti-democratic regime ?
This would be the end of UbPorts foundation before it even has fully taken off.
This also nicely demonstrates the importance of being a foundation registered under German law because any activities in such direction could be in conflict with the foundation by-laws and objectives.

I tried to pair my Nexus 5 with my car's (Subaru Forester) audio system via Bluetooth. The phone detects the audio system but there is no dialog box to enter the PIN from the audio system in the Bluetooth setup. The audio system thus refuses the connection request. Is there any work-around for this ?
Thanks.
