Bluetooth Pairing a Blackberry Pearl

Good Afternoon all,
 
I have a Mercedes E-Class 320, and I have been trying to pair a Blackberry Pearl 8100 through bluetooth with little success and I was hoping someone could tell me where I have been going wrong.
 
I have been following the manual as best I can, so...
 
I have the key in the car and the COMAND Console on.
 
I intially do a search on the Blackberry for devices through bluetooth which finds the car,
 
On the Car I then go into the Bluetooth and search for Mobile phones and finds the Blackberry (at this point has the square box next to it without being filled), I press ok on the console and am prompted to enter a passcode, so I enter one.
 
I am then prompted on the Blackberry to enter the passcode which i do so the car and the phone are paired.
 
The COMAND console then says 'connected' as expected, but after a few seconds then says 'not connected'.
 
The bluetooth on the handset is permenantly turned on .
 
I have tried deleting the car from the Blackberry and vice versa then re pairing the device, with no success.
 
Could someone please tell me if I have missed something blantant out, or offer me their instructions to pair a phone to the car (as I havent found the instructions to be very helpful, otherwise I would have done this by now!)
 
In advance, thank you for reading and any help or feedback will be greatly recieved.
 
Kind Regards,

Hi,

You may want to see this. Had a similar issue in pairing a Jag, this solved it. It's not for Mercedes but may be worth trying. I will be trying this for one of my colleages who has a CLK.
