New to the forum. I have just purchased a Grandland X and want to install a Dashcam. I have a hard wire kit, . However I'm wondering which fuse to Number to use so that the dashcam turns off when the ignition does. I would also like to change the wallpaper the on the Infotainment System. I have seen how this is done on a Vauxhall Corsa Infolink system and wondered if anyone else had tried this? Any Assistance gratefully received Mark
