Bluetooth phone link drop

[FoxyGTO3R]

Hi,
I have an 07 V8V with Bluetooth. At start up the little voice says "phone 1 ready", at some stage later the Bluetooth link drops out and when I try to make/receive a call, the voice asks me to pair my phone (I have an iPhone 4S which appears to be ok), also the small Bluetooth light just in front of the gear stick isn't lit.
Any ideas on what it could be would be much appreciated.
Thanks

Put the iphone Bluetooth into search mode.
Tell the car - Pair phone
Car tells you to put phone into search mode and then type 1 2 3 4 as the bluetooth code.
Phone will see the car - will list as Aston Martin. Put code in
It will then fail! Car says pairing failed.
But you now have the iphone recognising the Aston Martin bluetooth, so on the phone, select "Aston Martin" on the bluetooth menu. It will bring up the boxes to put in the passcode. Put in 1 2 3 4, but do NOT press pair on the phone yet.
Tell the car - pair phone. Then immediatley press the Pair button (top right) on the phone.
Should then pair straght away.
Checked and phone is always then recognised on startup

Hi Neil,
Thanks for your reply.
My phone appears to pair ok initially, but then the Bluetooth link seems to drop out for no reason.
Guess it's the car end of the link that has the issue, my iPhone Bluetooth signal seems fine?
Any ideas what could be causing this?
Many thanks.

What version of IOS are you running?

Would still follow the steps above, including deleting the phone on the car and re adding.
