Hey guys, I've got an SV6 sportwagon and have a remote head UHF. I have 3 questions that hopefully someone has come across. 1. Is there Retained accessory power in the boot with the battery to power the radio? 2. Is there a grommet or a way to get the coax through the firewall to the boot? 3. Surveillance mode - has anyone been able go install a switch or similar? apparently it only needs to be grounded for it to be active? just wondering if anyone could shed any light on this one? Thanks in advance, Adam.
