Just got a Prius last week. After researching all the options I'm getting close to putting in a ipod ready stereo. Bummed about making the audio screen and built in stereo defunct but the trade off is great ipod functionality compared to the ipod integration solution (which has lag time and due to the head unit limits on playlist/song capacity. The unit I'm thinking of is the Alpine iDA-X001. Anyone have any suggestions, comments, experience w/ this topic? On the buyer's remorse side I'm wishing I plunked down the extra money for a package 6. Now, I feel compelled to "make it up" by getting an aftermarket nav system, bluetooth device for my phone and to get an alarm installed. It would have been better to have it all integrated but as I understand it that is not doable (except for the alarm, I can buy the module from Toyota and have it installed.. thanks for reading my post!
