Rhett Posted June 26, 2008 Report Share Posted June 26, 2008 I have a May 2006 Z1 and the screen is starting to freeze on boot . If I put in the firmware fix will I disable the parking brake bypass ? Also if I do the Gracenote update will the bypass go away? My unit has been great so it's been a while since I've browsed the forum . I don't want to introduce another problem if I install these updates . Quote Link to post Share on other sites
garrettoomey Posted June 26, 2008 Report Share Posted June 26, 2008 The updates will not change your 2 wire bypass. You may also want to upgrade your system to a Z3. See the upgrade forum: http://www.avic411.com/forum/viewtopic.php?t=14899 Quote Link to post Share on other sites
Rhett Posted June 26, 2008 Author Report Share Posted June 26, 2008 Thanks for the reply . I read the link and also your classified . I may just send you my hard drive and let you do your thing . The price is definitely right . Would be great to have the latest/greatest "stuff" . With security disabled does that mean mp3's can be added ? Quote Link to post Share on other sites
garrettoomey Posted June 26, 2008 Report Share Posted June 26, 2008 You can not add mp3's directly to the hard drive. Unlocked and security turned off means that you can connect the drive to a windows based PC for future upgrades. Quote Link to post Share on other sites
