Hi all,

New to the forum. I have an E46 M3 with the MK IV nav system.

It continuously loses its location, then after 1-2 weeks, it suddenly finds itself again.

I have just updated it to the v32 software, but that did not fix it.

I note that I've got the ANT OPEN message, and no satellite info as shown below.

What could be wrong and how can I fix it?

Thanks in advance.
