I enquired with Toyota, who won't fit the Nextbase cameras I have, as I didn't buy them from them. They recommended a local audio company which they use nearby who could hardwire them for £180! So, as it's so expensive, I've decided to try running the wires myself just into the cigarette lighter, but I won't use parking mode and will unplug when I'm not driving. Hopefully the battery won't be run down - I'd want to remove the camera anyway when I get out in case it was stolen. I also won't use Halfords from the bad reviews I've seen, plus initially they said they wouldn't hardwire hybrids then they said they would, so I don't have much faith in them! If it's too difficult for me to fit, I'll probably then get the recommended audio place to fit them.
If I'm not using 'parking mode' and unplugging when not driving, does anyone know whether using the cigarette lighter socket is more or less likely than hardwiring to run the car battery down, when driving infrequently and for short distances, or the same? Is the normal battery in a hybrid (not the traction battery) smaller than other car batterys? If so would it drain quicker?
Thank you for all your advice
