    The car is a W204 2014(pre revision) C180 1.6cgi

    So I installed a dash cam and hard wired it. It works.

    The doors won't unlock via the Radio, but works perfectly via IR. Oddly the doors lock via wireless and IR. The car starts and runs fine too.

    I guess it something to do with the dash cam installation and yes the power was interrupted during installation.

    Any ideas?

    Disconnect the dash cam and see if RF operation resumes?

    Thanks for the quick response. Thats the first thing I've tried and no its still not working.

    Using Fuse 46 & 76 and they are not related to doors according to the diagram I used.

    In the light of day all comes clear. The fuse must have cracked when removed/inserted. So when i tested it out of the car all ok. when inserted in stopped working! Did spot it till today!

    thanks anyway
