Hey guys I was planning to take the seats out of my g35 to make sure everything was connectted under the seat. I am going to disconnect the battery and I was wondering if that would affect the Z1 in any way. Would all my presets etc be lost???

 

Yes you would hae to reset all of your audio presets, and all of your radio presets

 

And all of your audio settings on the custom eq functions.

 

Will I have to activate the navigation again? I remember the guys who installed it had to drive it around so the nav would find the location we were at since the nav when started was in Los Angeles.

 

From my experience no just the custom eq presets and radio presets have to be reloaded.
