I have a promotional subscription for Sirius/XM satellite radio in my vehicle that will run out in a couple of weeks. I don't intend to renew it but plan on using MP3's vs. relying on terrestrial radio stations. I do have a smartphone that I sometimes use as an MP3 player, but it would be nice to have one "permanently installed" for the sole purpose of just that. No bluetooth so I have to run an audio cable from the phone to my car radio's Aux Input plus I have a powered holder I also use to save the battery. I'm always carrying my phone around so it's basically a PITA to always connect it. #firstworldproblems Anyone use a cheap smartphone just as an MP3 player? Any recommendations? I already have a 32 GB microSD card I can install in it for extra storage. Don't need anything fancy, my holder works great for 4" screens.
