"There is not one automaker that every radio they produce will read every apple product! Thats a Fact"
Ok, thanks. That's kind of crazy about Apple wanting to require chipsets in the user device like a head unit (??).
I've noticed aftermarket iPod adapters and home docks, etc. support quite a few iPod models; that's more along the lines of what I was referring to.
I guess whoever buys a Sonic w/MyLink will basically just need to pick up a compatible iPod to keep in the car for that reason. Oh, well. eBay it is...
