When upgrading from vista to vista>go to dells driver and download page and download the patch for the 355 BT module.This patch is for the upgrading of OS either from vista to vista or vista to xp.

I installed the driver but my Bluetooth Audio still doesn't work, is it this link:

 

 

Or do you know another one?

No that is the original release,there is a 355 patch it shows up in my drivers section and it is for what i explained in the first post.

Ok, I ran the patch, a black Command Prompt screen came up then went away in half a second... I checked the version.txt and my computer wasn't in the computer list. It also said use that patch if Bluetooth was Disabled. I don't think i worded my question correctly.

 

My Bluetooth is ok, but i don't know if i can use it for audio (e.g. Bluetooth Headphones, Audio Gateway through phones) because i don't see the Bluetooth in my Audio Settings anymore.

Has your BT been disabled or turned off then?...Open control panel and then click on device manager,then click the (+) next to sound,video and game controllers and see what is in the list or if there is a yellow exclamation mark next to both of the BT items.

Nope, they're all on.

Nevermind, its fixed.
