Advanced Car Eye 3

[magyosha]

morning gents & ladies
was at my local bmw dealer the other day and noticed the retrofit option for 'advanced car eye 3' dashcam ..
considering having it fitted to my bmw 730ld f02 2015my. front and rear for £470 fitted.
however just wondering if there are better other options that either do more, are better quality or any other reasons to get something else.
its the front and rear option i'm looking at, sadly it does not seem to intergrate with the reversing cameras that are already on the car (rear & side) as that would of been nice.
