I've read a few posts on here about cutting a wire in the ISO loom (stereo side) to fool the MFD into keeping the date on all the time when an aftermarket head unit is fitted. I am planning on fitting a Clarion unit soon. Standard ISO connectors etc... No steering wheel controls so not worried about that end. Have heard though that cutting this wire can effect radio reception as it also powers the amplified ariel on the car.
So to confirm:
1) Is it the blue/white wire that needs to be cut in the ISO connector? If not which one is it as have seen some conflicting advise on this. The Clarion loom has a V with two blue/white wires - one going to the connector and a shorter one ending in a spade and not connected to anything at all.
2) Is cutting this wire likely to effect FM reception much or at all?
3) Am I better off leaving well enough alone and just putting up with no date on the MFD?
