memzey

Nicely done Entwood. Can you shed some light on where you placed the generic antenna please? If things change at my end, I might need to do the same.

I had a similar experience today but a better outcome - at the moment that is, touch wood it continues to work. I took the A/C control and MMI units out and tried to find a useful location inside to fix the generic antenna to. Very limited options, as you say, unless one is willing to take off other bits of trim and chase cables through (I wasn’t). I decided I would put things back as they were and place the new antenna in the roof lining by using the existing extension cable to the shark fin. Once I’d put everything back together again I thought “just give it a quick test memzey to see if anything’s changed “ and lo and behold it was working fine! 9 satellites being picked up no less!! I suspect my problem was the cable connection to the back of the MMI unit which may have worked its way loose, there was definitely something awry with it at first. All good now though apart from my endeavours have triggered the airbag light on the dash. I’ll try to pop to my mechanic in the coming days to get him to reset it for me as I don’t have an ODB reader - unless someone on these boards knows how I might be able to do it myself?

Thanks Entwood. My sat nav has me somewhere off the coast of Cornwall rather than where I actually am (London at the moment but normally Hertfordshire). I read about people checking how many satellites their unit is connected to. Does anyone know how to check this? I suspect it’s a shark fin antenna issue but am early in my diagnosis.

Can you provide a link to this article please?

Hi everyone. First post, glad to be here. I have the same issue on my facelift C7 Avant. Is there a guide on how to do this fix, including removing the MMI unit that anyone can share please? My car is a late 2015 model. Thanks everyone!
