I have a 2001 M5 with Mk3 sat nav and wide screen monitor. I have upgraded to Mk4, now all I have is a black screen on the monitor.

Any ideas whats up. Thanks

Either the Nav is faulty or coded for the Business Nav system.

Return the Nav or get a copy of NavCoder and a resler interface and see what the coding is.

 

[BM-Rod]

It is a business nav. Please explain how I get this to work.

 

[RichardP]

Buy a Resler iBus interface IBUS Interface for BMW cars or find someone near that has one.

Download a copy of NavCoder NavCoder Website

Use NavCoder to recode the Nav from Mono to Colour, you will need a Nav software CD.

 

[BM-Rod]

Would you do this for me if I send the nav over to you. Nobody over here would know what to do, me included.

 

[BM-Rod]

I have pluged in my old fried Mk3 and no longer have the blue screen which I did have. The screen is black but the back light seems to be on.

 

[RichardP]

Do you have the TV module or Traffic Master system?

I can re-code the Nav for you if you want, but are you sure there is no one a little closer the Nav is quite heavy and expensive to ship around if you don't need to.

 

[BM-Rod]

Yes I have both Traffic Master and TV. When I press the TM button a Map comes up on the screen.

 

[RichardP]

Might be worth bypassing the TM and TV in turn, they just daisy chain, so start by connecting the Nav directly to the blue plug that ges into the TM box.

 

[BM-Rod]

How exactly do I do that.

 

[RichardP]

Basicall disconnect the blue plugs into each unit, connect the units into the blue plug on the car harness (the one that goes into the flying lead on the TM unit), Nav first, then TV.

 

[BM-Rod]

Tried this with the old Mk3 unit which I know had a blue screen but still nothing. What does this mean now.

 

[RichardP]

Probably that the Mk III was faulty and the MK IV is incorrectly coded.

However, try this. Disconnect the Nav computer completly. Turn the ignition on for a little over 1 minutes, then turn it off, wait 1 minute and turn it on again. Do you see anything on the monitor? The TV module should kick in to provide a basic UI to control the radio, OBC etc.

 

[BM-Rod]

Done this Richard and I now have the basic blue screen that I used to have with the Fried Mk3. What should I do now? Get the Mk4 properly coded.

 

[RichardP]

Yep, coding the MK IV correctly would be the next move.

 

[BM-Rod]

Would you pm me your contact number Richard. I would like to speak to you about programming this nav.

Thanks
