Going by what coastaletech's page says: ( http://coastaletech.com/DELUXE_LOCKPICK.htm ) 'As as added bonus *** The ULTIMATE LOCKPICK now provides support for the new 2007 XM TUNER *** Connect the new 2007 XM tuner to your XM ready TOYOTA/LEXUS and the LOCKPICK will unlock all 16 CHARACTERS OF TEXT FOR YOUR SCREEN. (without it, the 2004-2005 and most 2006 screens will only show 10) - No more half titles : )' Is there anyone with the Integrated Sirius and this ultimate lockpick? Does it remove the 10 char limitation from the MFD? I actually e-mailed coastaletech's support but received no response after 3 days...
