Bit of a car noob, just bought a VYII Executive and looking to replace the headunit. I already have bluetooth connectivity which is one of the important things for me, but I am looking at getting a reverse cam fitted and GPS. Am I better off getting kind of an 'all in one' type of head unit or should I get a separate GPS, separate reverse cam (perhaps the rearview one) and keep using my current headunit? If there are decent all in one type things, have you got any suggestions? Thanks in advance.
