I found this link by accident... http://www.toyota.com.au/accessories/audio...llitenavigation It shows the 100 series navigation unit and says... "The intelligent system includes a four-in-dash MP3-compatible CD Changer with Bluetooth™^ communications, giving you safe, hands-free access to your mobile phone. Nowhere in my instruction manual does it talk about bluetooth. Was this something that Toyota did for a while and then discontinued? Is there a hack that turns this on? Any thoughts? Glenn
