bcdal Posted May 13, 2012 Report Share Posted May 13, 2012 I have an original Z1 upgraded to a Z3. The gracenote says to apply the firmware update to a Z3 only. Anyone know if I should try use the firmware update? Says it could damage the Z1 and Z2 units so I'm not sure. Thanks Quote Link to post Share on other sites
jwq Posted May 13, 2012 Report Share Posted May 13, 2012 a Z1 or Z2 upgraded to Z3, becomes a Z3, there's no difference to a unit that started out as a Z3. So you can use any software meant for the Z3. Quote Link to post Share on other sites
