Problem with Bluetooth working on SE k750i
 

Hi,guys. I have BMW 320 e46 [09.2003]. I have bluetooth module in my car.
My phone is SonyErricson k750i. The software of phone is R1AA008.

I have succesfully paired the phone with BMW. All is good. But sometimes I have a freeze of my k750. The phone freezes and dont react on my actions. Only if I pull a battery out and in, he works.

Why I have this bug? Is anyone have this bug? How to fix it.

Thanks in advance.

P.S: BMW Navi Software updates only Navi or bluetooth module too?

Hello zemelya!

I has this problem on my X3 with 13Gen ULF module weekly ((
ULF module changing does not solve this issue.(((
Phone software change does not help(((
When you do a Navi update - you add new software to MK4(or MK3 or MKx) Module only.
In old (not MOST) cars ULF, Radio, Tv modules are not programmable.
They can be only coded.


With my new SE K800i Problem dissapeared. )))

Regards!

So you recomend only to change phone? :)
Have you tried other phones with your Bluetooth module? I need the statistics of worked phones to have some сhoice before I buy new phone :))

It very depends on what ULF module Version you have.

I am SE fan an as i remember T610 was Ok with BMW Bluetooth.
Nokia 6310i is of course the best and stable phone.
Bmw people uses 6310 for checking purposes.

Regards )))

How to know what ULF-version I have?

Post the P/N and we will tell you. Or do some searching here or on bimmerboard.com

What is P/N? How I can find it?

Part Number, you can find it on ULF module

It will be 84 21 x xxx xxx on the tag on the side of the module.
