I definitely feel you on this one, buddy. The car/GPS situation without a bluetooth connection is where the lack of a headphone jack really hurts the most it seems. My less-than-ideal solution would be to just bring your own bluetooth speaker. It definitely won’t be great for music, but it should at least be passable for podcasts and any spoken stuff, so it should make your drive a bit more tolerable and help keep you awake. I spent years keeping a small bluetooth speaker in my 2007 Prius before finally having a bluetooth receiver installed (definitely worth the money). Safe driving!
