Help ! (Title says it all.....)

tdaniely · #1 12-19-2005, 12:52 PM

Although, I don't own an X5, I do own an E38 (740iL) and am having problems with the NAV O/S Updates.

Here's the story:

First, I completed my virgin navigation retrofit into my 96' E38 using a complete MK1 system.

The system functioned flawlessly.

Next, I decided to upgrade to the latest O/S using a V26 disc (which installed 1/80 on the MK1)

Well, the interface looked much prettier, however, as soon as I turn off main roads, I get "correct dest. guidance not possible" displayed across the screen and the computer stops giving audible guidance prompts, ALTHOUGH the route to be traveled is clearly indicated on the screen.

I went to the local dealership and dropped all the way back to a V8 disc and the system started working perfectly again, so I left the O/S at V8 and all was well.

I've recently finished an MK1 to MK3 upgrade (soon to be MK4) and all was well again, however, I really like the split screen, so I upgraded to the latest O/S for the MK3 (which is 1/63) and the same problem happened again.

Streets that the system ONCE was able to give guidance on, magically are no longer "digitized", according the the system.

I need to know one of three things

1) How do I correct this rather annoying issue, since most of my traveling is back roads ?

2) Will the same thing happen on my MK4 when I install V26 ?

3) Does anyone have an O/S disc older than v.18 that I can use to restore my MK3 to an actual functioning status ?

Thanks !

Hi Tyre,

On your nav screen in the upper right hand corner should be a small box with the corner of a globe. Are there any green dots appearing in that box? If so, that is an indication of how many GPS satelites your receiver is seeing a signal from. If not, then you aren't receiving any GPS signals and the system isn't able to guide you.

You are probably aware of this, but the MkI has a separate GPS receiver module that is a completely different component from the nav drive. With the MkIII the GPS receiver is built-in and the antenna connector would go directly from the antenna to the MkIII drive unit.

It's likely that the problem you are encountering on the MkIII will also be present on the MkIV, so let's see if we can get this figured out. There's a diagnostic screen that you can access. See http://www.xoutpost.com/showarticle-164.html for details.

I'm also going to send you a PM with a source that has a copy of V15 and V18 OS.

and let us know how it works out.

Jeff

The antenna has already been moved to the MK3 unit.

As I'd indicated, the system worked flawlessly before the O/S update.

Also, when I see the message "correct dest. guidance not available" the system has fully acquired all satellites. "GPS" is fully lit up.

All the hardware is functioning fine, there just must be a huge glaring software bug no one has noticed yet.

I get the "correct dest. guidance not available" on certain roads in very rural areas. These are roads that NavTeq isn't completely done "digitizing" yet. For me it's much more the exception then the rule.

Okay that's understandable, but like I said, the roads that are coming up as NOT DIGITIZED were not a problem BEFORE I updated the O/S

Before the O/S update, I could drive these EXACT SAME ROADS and get guidance the entire way.

Now, I can drive the SAME ROAD using the SAME NAV DISC (2005.2) and with ALL satellite signals acquired (GPS Lit) and not get guidance.

This is a definite bug in the O/S, but no one has really noticed, save me.....

Hello

I do have the same issue happening in my X5. I think that it is not any OS dependent issue. I have updated several operating systems and that symptom has always existed in my navigation system.

However, I've noticed that the route magnet feature has something to do with it. When you start your vehicle in a rural area (with a route magnet set on), the navigation system gives you audible insructions, but it does not show instructions visually. When you start your vehicle off-road (and the route magnet is set on), the navigation system gives you both the audible and visual instructions. However, when you the go on to any "digitized" road and then come back to "not digitized", the system does not give you instructions anymore.

I think that the reason is either a bug or it relates to some settings. I do not know how to fix it, but I would be very keen to know.

I'm willing to bet you probably never had an O/S older than V17, however.

With each NAV system I've had, it always functions fine until I update to newer than 17.2

Sure, the interfaces are pretty in the newer O/S, but at the loss of function.

I'll be able to post a DEFINITIVE answer on Saturday, as I will be obtaining another V17 disc (my last one got corrupted)

If I drop to V17 and all is well, then I've found an O/S issue no one else has either noticed, or cared to complain to BMWNA about.

Keep watch on this post.....

Thanks man !

Your friend contacted me last night and will have a V17 disc waiting on me when I get to the dealership on Saturday.

I was surprised they'd be open on Christmas eve.

'ppreciate it !!!!

Tyre,
It was nice chatting with you last night, and I'm glad to hear that you are all set with your appointment on Saturday. I hope the V17 load helps narrow down what may be happening.

Note that on the MkIV nav computer, the first supported release for that unit was V20.1. Thus, when you make the jump to that nav drive then that will be as far back as you can go.

and keep us posted on your findings.

Jeff

Yep. My first nav OS version was 4-1/12 (V21).
