Nav/GPS issues

[greg81]

Big improvement this morning. My correct location was locked quickly this morning and the map followed my moves pretty accurately.

Still getting a false value for Almanac but will keep an eye on it over the next few days.

Don't think there'll be any interest but I'll write up all the steps I took to resolve this as I couldn't find any useful guides anywhere!

How did you get to that service menu?

- Go to top menu
- Push dial to up for 10 seconds
- 3 clicks to the right
- 3 clicks to the left
- 1 click right
- 1 click left
- 1 click right
- 1 quick depress of the dial

Go into settings, scroll to bottom and it should be there

That was obvious, how did you find that?

The wonders of the internet!

So I think I'm resolved however I need to wire this bloody thing in now which is a pain. Tempted to see if any breakers have the receiver as it simply unplugs are the back of the rearview mirror so if my loom is ok it would save masses of effort!

The almanac could be one of two issues..failure to get a good signal for long enough to update or..

Sometimes the memory that keeps the almanac goes bad and it gets either corrupted and/or loses its ability to store the almanac..

In which case a replacement receiver is the only long term solution..

I wouldn’t have minded having the nav on my soon to land 30i, but only really wanted it for the parking aid side of it.
Hope you get sorted Greg
Bring on the train ride Monday

Just revisiting this after a bit of time away...

Is it supposed to be held together by this sticky black stuff with broken clips? Looks like an autoglass special to me...

[greg81]

Some top work right there

[greg81]

This story continues but I'm confident of a solution now.

The antenna has a female connector so I can't use the cheap GPS cable to plug into it, however I can get a pre-owned replacement genuine BMW unit for £20 on eBay that I can plug into the cable able the dome light and not have to bother ripping the dash apart to fit a new wire

[Pbondar]

Good detective work...the curse of bodging windscreen fitters...

[greg81]

Well, I'm pleased to say now that this chapter is now complete.

New genuine used GPS receivedr arrived in the post today and I connected it above the dome light. No wiring required. Plugged it in and an almost instant 3D fix.

Phew!

Could you advise if getting out of the service menu simple please?

After having troubles with the system in my car - the dealers “expert “ told me that only workshop kit was able to identify satellites aquired etc. I suspected bs at the time and this has confirmed my suspicions !

Hey, happy to help, but I don't think I understand the question?

[ronk]

I had trouble with my sat Nav when the position arrow wasn’t on the planned and highlighted route.

I suspected that the system wasn’t locked onto the satellites. I explained my thoughts to the BMW techie and asked if there was a method I could use to interrogate the system - he told me it was only workshop kit that could do this task.

Your method shows the method to extract the information from the system should this happen to me again - however I’m unsure how to get “out” of the system and return it to its normal running status.

I don’t want to try an interrogation and screw up any of the current settings.

[greg81]

Ah, I see what you mean. The menu you access with that procedure I listed above disappears after you stop and restart your engine , and there's nothing you should need to do to get out of it.

Not sure if you're done the procedure to get in to it, but all it does is add some extra options in "settings" rather than lock you in to some kind of hidden area.

Are you still having trouble? I've got a replacement antenna I bought for eBay that you're welcome to have if you think it's worth a try

Your offer is appreciated.
My problem started last year when I took the September 2016 car to Germany immediately after having a BMW dash cam and it’s windscreen mounted antenna fitted. I suspected that there was some conflict between the systems.

They moved the antenna for this years trip and it was mainly successful - it went off route near Schipol airport. At that time I suspected that I was lacking a good lock. It would have been good to have a look.

I’m not away to Europe in the Z4 until July/Aug 2019 but your script will enable me interrogate the system should it go off route next year.
Unfortunately they have fitted a later model camera to further muddy the waters!
