I've been looking around for a reliable decent bluetooth streaming solution...
I have a Sony MEX head unit in my wife's car, but don't want to move it over, because I'll have to buy a new head unit for hers, and a fascia for the Stilo, and then I know it will creak and rattle once it's installed, and the wiring will cause issues... so here's my latest solution...

I picked up a Nexxus DriveTransmit Pro on offer at play.com for £15... (http://www.play.com/Mobiles/Mobile/4-/13863959/Nexxus-Drivetransmit-Pro-Bluetooth-Hands-Free-car-Kit-With-FM-Transmitter/Product.html?searchtype=allproducts&searchsource=0&searchstring=nexxus+car&urlrefer=search) tried it plugged into the cigarette lighter and it' was excellent, so I relocated it to next to the steering wheel and hard-wired an inline lighter socket... it's an FM transmitter bluetooth device, and the FM signal really is crystal clear.
I managed to wedge it in below the small storage bay behind the indicator stalk, so no permanent disfigurement of the dash...

That looks like a good, neat solution and also allows you to add a 3.5mm jack input, I think I'll try one.
Just looked on the play site and it's £24.99, did you get it on special offer?

Yeah, it was £14.99 when I bought it - I was going to get a Jabra Cruiser, but I'd never have used the speaker. I wanted a device with a decent FM transmitter to stream music from my phone without cables and without replacing the OEM stereo.

On offer again at Play.com, sixteen quid delivered.
