It seems smart phones are losing regular headphone jacks, and my ancient car doesn't have bluetooth support.

With any luck, I'll be replacing my phone before my car, so I'm looking for an adapter that will let me plug a bluetooth receiver in to patch my phone into my car stereo.

I've seen them from $20 to well over $100 (with DAC and amp built in). Anyone have any experience with them?

thanks,
