i have a car with a stock stereo, no Aux or BT. I'd like to be able to listen to podcasts from my iPhone. I was going to install an aftermarket stereo, but it appears to be a pain to install and keep the factory steering wheel controls which kind of hate to lose. Is there another solution to add Aux or BT? Otherwise does anyone use a BT Speakerphone, like a clip on the visor type? Or some other speaker? I'm tempted to just get a portable speaker and I can leave it in the glove box when I'm not using it.
