Hey guys, I have just bought a head unit from JB Hi-Fi 2day and gonna get it installed by them next Tuesday. There is an issue that had been troubling me from the drive home.

Because I have brant in my bug eye and the installed will probably disconnect the battery during the install so I was thinking that it might screw up the alarm when he reconnects the battery.

I would just like to ask what is the right way to install it without screwing up the brant so I can remind the installer? Btw I was told that I have an upgraded brent from subaru when mine fail and they updated it for me.

Cheers
