SE K750i doesn't work with newest SE firmware and Nav system

ADerber · #1 04-26-2006, 04:05 PM

Hi

I have the newest firmware (R1BC002) on my Sony Ericsson K750i and the correct snap in adapter for thi phone. The X5 is built on januar 2006 and therefor quite new too.
Not all adresses from the phone where syncronized and the voice won't be work on the nav system (SA 633).
On the sony ericsson forums it's described to downgrade the firmware (f.e. to R1AA008). On the other hand it should be possible to upgrade relavant bmw firmware. The nav firmware itself is also up to date. A brother of me with the same nav system gave me a cdrom a few day before with the newest firmware (out of this navigation forum)
Is there any experience what to do or should i contact my bwm support in germany?

Thanks.

Axel

Do you have this in a E53 or E90?
Got any pics?

Hello,
the correct part number is 84.21-9 116 566-01 from Austria. Revision 01 is built at 10/04/06.
Where can I find the E-number? I suppors it's a E90 because i order this car at november 2005 and the first date of official use is januar 6th in 2006. So it must the newest model (and therefore an E90).
Don't know what picture to make. The bluetoth connection between car and phone is established everytime i enter the car and the connection is closed everytime i leave the car. I can address the phone book (without some leaving entries) in the nav system. Now when i dial a number the radio plays no longer music, but when i try to speak over the car loudspeaker or car microphone i doesnt heare anything and i won't be heard. When i took the mobile directly i can talk normal (but without car "free speaking system" - the radio is still playing no music). When i then finish the call the music starts.
I'd talk to german bmw customer service. They told me to upgrade firmware or downgrade mobile. The next car firmware might be available with next mobiles or new car model (end this year). I don't want to wait and hope.
If here's noone having any ideas i try to downgrade my mobiles firmware.

There is no way to downgrade your firmware without sending the phone into SE. You can use the updater to update it on your computer. I just wanted a pic of where your phone goes into the snap in.

Hi,
thanks for your quick reply.
Do you still need the picture?
Upgrade the "car firmware" is no alternative way? No chance? No hack?
Any other chance than downgrading SE?!

A picure would be great please.
If you have a local SE center; they can downgrade your firmware.

I have R1N035, right now and have no problems. R1AA008, R1NA005, and R1AA008 or options to downgrade too.

Sounds very familar Axel. I have the BT/Assist TCU from 9.2005 in my M3. I have exactly the same problem you describe with the latest Sony Ericsson W810i. Most address book enteries get transferred ... but some dont. Audio doesn't work through the BMW system. Its a real shame since this new handset is great !

I would like to see a photo of the snap in too. The 810i is supposed to be available from Cingular in the US in June or July and I'm thinking this is the phone I'm going to get. I'm wondering if the snap-in for the K750i will fit this phone. The antenna port looks liek it is in the same spot and the charging portion is the same.
