MKIII SAT NAV to MKIV

[JG42]

Bought a 4.41 a couple of weeks ago. It's fantastic but now I want to upgrad the Sat Nav from the MKIII (V17.1 3-1/31) to a MKIV. I understand that it's a simple Plug & Play swap? I've been offered a MKIV with a part number of 6590 6 951 629-01 and would be grateful if someone could advise me if it will work in my car?

I can confirm that going from a MkIII to a MkIV is a simple plug-n-play swap.

As for the compatibility of that particular MkIV, hopefully someone with a current ETK can check the numbers for you to verify. But in general, if the MkIV came out of a new style 5 series or 7 series then it will not work (those have an optical MOST bus). However, if it came out of an e46, e38, e39, or e53 (these vehicle have the i-bus) then it should work just fine.

Thanks for the reply and my apologies for not responding sooner. I did get the MKIV and it works fine. The guy who sold it to me also sent me the V26 software so I have a great looking map. Only one small glitch, the BMW logo doesn't come on when I unlock the car or open the door. I sometimes comes on when you turn the ignition on.

I was prompted to get the MKIV by what you had written and I'm so pleased I did.

Now I would like to convert the factory installed phone to bluetooth. I've asked several BMW dealers if it can be done. They say I would have to have a completely new system installed at a cost of £1500 (about $2500)! The existing installation takes a Motorola V5 only. I can't beleive a manufacture would be so short sighted as not to alow for furture developement. I have a V5 (don't know what the US equivelent is) and, although it's ancient, it works fine. I also have voice recognition installed. Someone somewhere must have produced a small bluetooth module that you just plug-in in place of the existing phone (which is located in the centre arm rest)?

I'm not too technically minded and wouldn't like to attempt some of the stuff you've done but having read just about everything you've written I'm hoping you might be able to point me in the right direction.

Just got my new registration X5 JKG!

Thanks again for your great advice.

Thanks for your good wishes and advice. I had already seen this part of the site but couldn't figure out which of the articles relate to my situation. Bearing in mind that the original phone/mic and voice command system came with the car when new, could you point me in the right direction! I thought the article from UCrewX5 might be the right one but I'm not sure if he (Jeff?) had a factory fitted phone in his 2001.

Could you advise on some of the terminology please? What is a ULF. What and where is the DB25 phone connection. I've only had this wonderful machine for a few months and, as you can probably tell, I'm not that technically minded.

My 2001 X5 did have the phone prep, but did not have the phone system installed.

The ULF is the bluetooth control module - the brains behind the system. This used to be called the TCU (telecommunications control module).

The DB25 is the type of connector that was in the earlier vehicles. It is a 25 pin connector.

Thanks for the information. I'll get intouch with Advanced Autovations to see if they can provide what I need.
