How do!

I am at my whits end with my MFD unit. Worth mentioning before I start that everything worked fine when I installed it along with the plug and play adaptor. Trouble I have now is that it doesn't power down or up with the ignition. But it is receiving power and all radio stations are stored fine. So after some further investigation on here it would point towards a ignition wire fault. Checked the connections from the unit back wards and everything is fine. Check from headunit right to fuse box. Strangely fuse 37 I think it is had blown s-contact I think it's called. In the manual it says this is used for radio and a few other items etc. I also checked Radin fuse 42 and that was fine.

As its an mfd do I have to do what others have done with aftermatkets and swap over the live and switch cables? If so its weird that it worked before and looking at other installs the MFD works fine so long as you use the plug and play adaptor which is what I have.

So having checked the cabling and replaced the 37 fuse aswell as check 42 fuse radin I am now stumped as to what else it could be. Any suggestions? What would cause the S-Contact fuse to blow? Thanks in advance

All sorted! Weirdly after 3 days of changing the fuse it now comes on with ignition.
