Any bluetooth trouble issues of 05' models?

[Kris@modmynav]

Hello,

I was using samsung D500 with bluetooth, worked fine except phonebook transfer.
but had to connect bluetooth manually everytime that I wanted to use, I thought that's cuz of my phone.
well, I got sony ericsson k750i which was on the bluetooth phone list,
and was trying to pair this phone with my x5 but it's keep getting fail messages. - I paired once only like 1 of 20 or more.
phone found x5, was able to add to my phone, but can't connect.
so I was wondering if there was any trouble issues for bluetooth, updated software or something else?

Thank you!

I know this might sound obvious but make sure your phones are visible to other bluetooth devices!
