I have the original tuner with cassette player in my dash and haven't really wanted to change it out as so far I haven't found a unit that looks like it would belong in that dash and be "friendly" to fat fingers while driving. But local radio is really bad and I don't have hardly any cassettes left from the old days. I looked at the available casette bluetooth devices and found one that looked pretty good several months ago.

Only problem was that it hadn't yet been released by the manufacturer

Well they finally released it and I just did my first short test in "Goldie"
This puppy works great!
Take note that it has only been a short test but the sound quality from my Galaxy to the unit both on mp3's on the phone and Pandora was fabulous
It does have a little mike that you can use for hands free calls, but it's not too likely I will use it.

Anyway; here is the link to the item. As of now they are selling direct:

Cassette Adapter Bluetooth - Bluetooth Music Receiver for Cassette Decks - ION Audio - Dedicated to Delivering Sound Experiences

 

That's cool. I think I'll get me one. $30.00 is cheap. Nice find.

 

I've got one of these and it's super cheap, works as it should and dont need charger...
