Hi, instead of buying from them, does anybody know roughly how much does the shop usually charge for installation fee if we bring our own smartmirror with dashcam and request them to install for us?

if we want the reverse camera function, we can only hardwire it to the reverse light? is there any way that does not required hardwire?
