Not surprised.
I bought a Prius, 'The Most Technically Advanced Vehicle On The Road', according to the salesperson.
Except...
If you bought the one that year that had the Sirius/XM radio, you couldn't connect the iPod to the radio, even though it had the USB connector open for the cable to plug in to!
Yeah...
In order to make the iPod work, I would have to perform surgery on the radio, and remove the satellite radio part, or kill the 6-disc changer somehow.
I even called the Toyota help line, and they just sighed and told me I should have bought the radio with navigation, because that radio does work with the iPod. I found out that I could have also gotten the 'standard' radio, but the radio in my Prius was part of a package.
So, no, I'm not surprised that Toyota is brain dead about their car audio units.
I've lived with it...
