Since for me usage of Traffic Message Channel (TMC) was like a lottery (rarely useful throughout whole year), and in order to avoid Internet connection, let me kind of dream about and just as a thought here; ideal-wise would be if Librem 5 GNSS Module (led by Pure Maps) have an additional capability (figuratively saying) of using DAB(+) in Europe or HD Traffic (Nord America) signals of Real-time Traffic Information over USB-C extension so that there, when driving, is no need for using the Internet (at all). Such HW/SW upgrade might bring Librem 5 v2 (or Librem 6) to the markets where professionals (with relatively old cars and, of course, buses & trucks) use the roads. As constant power source and antenna are important for turn-by-turn navigation I would suggest (as an example here and/or for an eventual future expert consideration) accessory for USB-C similar to Garmin GTM 60™ HD Digital Traffic Receiver or GTM 70™ Digital Traffic Receiver (Europe) even though direct integration of digital radio and processing system-on-chip within Librem 5 v2 may be cheap and quality infotainment/entertainment solution as well. Here is an intro (important) to Transport Protocol Experts Group (TPEG) Traffic and Travel Data via the DAB family of standards and here is (just as info) comparison of (Garmin) Traffic Service Differences for North American Automotive Devices.
