Car Bluetooth

sammydog01 thought this was worth mentioning said

I drove my poor old minivan into the ground and replaced it with a Honda CRV. Yay! It doesn’t have an aux-in jack. Boo!

I have a Fire tablet and would like to hook it up to the audio system and can’t figure out how- it seems to expect a phone. I like to play Audible, Chirp and downloaded Spotify music. Maybe some podcasts. Can I do it?

If not, is there a cheap phone I can buy? I prefer to not use my good phone all the time. Or should I just use one of my many Meh speakers?
