i wonder if anyone has this same thing happening too: every time i first get in and start up and the phone connects, after about a minute or so or maybe 30sec after i start driving the system disconnects with each other and then a few secs later will reconnect again. this happens EVERY SINGLE TIME like clockwork... sometimes even a few minutes later it will mysteriously drop out and then come back again, but at least that does not happen every time... i wonder if anyone else has that issue or not?

not a big deal but just annoys me sometimes especially a few times where i get called right when i get in the car and then the call all of a sudden drops

ok well end of my rant, give me some opinions.

should let the dealer check it out, mine stays connected throughout the whole ride.

What is your telephone handset model?

Bluetooth connection should be stable - from your description here the handset connects, loads contacts to you e60 then looses connection; unstable bluetooth connections of this type are invariably a problem with the telephone handset, your e60 is a later build and in my view would not likely be the cause.

In my experience its apparent that an increasing number, especially early/new to market versions of smart phone models, are prone to bluetooth problems of this nature - suggest you upgrade your telephone handset's software to the latest version possible (e.g. early Nokia E71?s and HTC Touch models bluetooth were prone to problems with E60?s until Nokia/HTC released updated handset software.)

i have a nokia n78... that does make sense, i will try to update my software on the phone first and see if that fixes it, thanks!!

I stay connected the whole time, but I noticed my car doesn't fully shut off unless I hang up the call.

no problems here with my BB 8330

+1 for checking for an OS/SW update for your cellular...another question..how many contacts are on your phone..A large number (250+ or was it 500+) can cause pairing issues as well..

My Nokia E71 has just started doing that (2006 520d), worked perfectly for the last mnth then since yesterday has started dropping the bluetooth connection repeatedly. No changes (that I'm aware of) to the phone. I've deleted the pairing and re-established it but no change. The E71 is on the latest version, and had been working perfectly up to yesterday.

No problems here. Sorry couldn't help.

just started having same issue with bluetooth...new lg viewty connecting and disconnecting and not pairing names etc ....have reverted back to old samsung and works spot on....i think issue is with some of the newer handsets maybe ?

I?ve placed this up notice on the forum before, here it is again ? no magic solution here however it may help to explain and provide a way forward with bluetooth issues where connection is unstable ? ultimately using unapproved handsets could cause the TCU into a false state which may preclude stable bluetooth connection, this as referenced below, read on..............................

SITUATION
The customer paired an unapproved handset to a vehicle and now has a complaint. Please use the information provided in this bulletin as guidance during the diagnosis and warranty process.

COMPATIBLE HANDSET INFORMATION
Visit www.bmwusa.com/bluetooth for a list of handsets that have passed BMW testing for compatibility. Note the following disclaimer on this web site:

? "This list is provided for reference only. The mobile phones listed here have passed compatibility tests as of the date of testing and meet or exceed minimum standards established by BMW. The list is not a warranty for phone performance or functionality. BMW makes no guarantees or warrantees as to the performance of each phone while connected to your BMW via Bluetooth Wireless Technology. Furthermore, software releases by BMW, the phone supplier or the wireless carrier dated after testing might alter compatibly results. While many phones are offered with Bluetooth Wireless Technology, not all phones support the necessary profiles to work with your BMW. BMW does not guarantee availability or functionality with all wireless carriers. Functions such as synchronizing the address book and transferring a call into or out of the vehicle may function differently from phone to phone".

UNAPPROVED PHONES
"Unapproved phones" means that either the handset has not been tested, or has been tested but a problem was revealed. Due to the length of time that it takes to validate a handset when a handset is initially available for purchase, it may not be on the compatible list, but could be added at a later date.

On some handsets, the initial handset software may have bugs which prevent normal hands-free operation and which prevent the handset from being added to the list. In some instances, the handset manufacturers are working on maintenance releases to correct issues and these may result in the handset being added to the list at a later date.

Here are some common issues seen when pairing unapproved handsets to a vehicle:
? The handset constantly connects and then disconnects from the vehicle.
? The phonebook does not download correctly.
? The phone book never finishes downloading. The radio or Control Display is stuck on the phonebook download screen.
? A phone call cannot be initiated or ended via the vehicle controls.
? The phone call has ended, but the communication menu shows the call time counter still counting and the radio remains muted, even after the ignition is shut off.

No permanent damage will be caused if an unapproved handset is paired to the vehicle, but it could temporarily put the TCU into an inoperative state.

Diagnostic tips for resolving communication issues after an unapproved handset has been paired to the vehicle

The following sequential actions may be required to resolve the inoperative state:
1. Power down the unapproved handset and remove the handset from the vicinity of the vehicle. Wait several minutes. This will allow the internal timer of the TCU to reset. If the problem is not resolved, proceed to step 2.
2. Allow the vehicle to assume sleep mode. If the problem is not resolved, proceed to step 3.
3. Allow the vehicle to assume sleep mode and then disconnect the battery for 16 minutes.

WARRANTY INFORMATION
Any repairs made to a vehicle which appear to have been caused by an unapproved handset being paired to the vehicle are NOT a warranty issue. An example of this is when the radio is temporarily muted because the unapproved device was paired to the vehicle, but once the unapproved device is deleted from the device list, the radio functions properly.

The following is an example of what would be covered:
? The customer has an unapproved handset paired to the vehicle and it has worked (with or without anomalies) for an extended period of time. Suddenly, the handset no longer pairs to the vehicle. When diagnosing the vehicle, the TCU has fault code 73, Memory Error. The unapproved device is deleted from the device list and an unsuccessful attempt is made to pair an approved phone.

All customer concerns must be verified with a compatible Bluetooth handset.
The unapproved handset must be deleted from the TCU paired device list.

After pairing an approved device to the vehicle, a short test using BMW Diagnostic tools must be performed and FASTA data has to be transmitted. If a warranty claim is submitted and FASTA data shows that an unapproved handset was in the Bluetooth device list during the diagnostic process, the warranty claim may be subject to a denial of claim payment.
