NAV system replaced but fault still exists?

Thanks for your reply, had a bit of an update. Took my car back into the garage while they reset / updated the car's software and was given a mini loan car.

Got a massive shock that the same issue occurs in their mini loan car 2012 model!!!

The road condition is very good and there are no bumps or pot holes that I can feel.

I checked the system time and date and it is correct, I'm assuming this is what you are referring to the main clocks binnical ?

The same exact issue happens with their car, car loses the signal and does not locate the signal again, sometimes it does if you drive around for 30 minutes other times it does not unless the car is powered down and back on again.

I guess this pretty much confirms that it isnt a hardware but a software problem! They have asked mini to investigate but I guess no one seems to have come across this issue before ?

I was to try removing the dash to see if I could try my own antenna but apparently removing the mini dash to get to the speedo is really hard.

Is there any kind of "code" that could be changed that tells sat nav to stop looking for a GPS for a specific time, like a timeout period ?

No the date and time in the binnical cluster are not the same as the date/time from the GPS signal (I know, I know), but is an inconsistency of the bmw system, you would think that they are tied together but they are not.

Check for satellites and the alminac in the Nav sevice menu when this happens, and see what it says.

Could be but I very much doubt it, you could try a v32 reload and see if that helps, are you running OEM firmware? (what version).

I still think its a dosgy GPS antenna, I'd be temped to run a temp one (an ebay £8 jobbie) on the dash and see if you get the same thing.

No, not possible.

I checked with MINI (Head technician) and apparently it is not possible to enter the alminac as no such menu / hidden menu exists on the MINI cooper 2012 so I cant view this.

Any idea on how to view this? I checked all the MINI menus and all it shows is the MAP Version (Europe 2012) but no OS versions. (I am using factory OEM version)

This is what I would like to test but do you know of any instructions on how to remove the speedo or access the antenna to try a different one?

The problem is that the navigation system never reacquires unless the car is powered down.

Here's a video of the problem in action: http://www.youtube.com/watch?v=z5hRZ...ature=youtu.be

I tried a tomtom in the same exact area and I have no issues here so it looks like its specific to MINI.
