Apps App that connects bluetooth put through loudspeaker?

[mitch04]

Hi I have a Archos Android And was wondering Is there a App that MY phone can connect through bluetooth and put through lound speaker on my archos?
The Archos has bluetooth support as well as mic. So For example:
Im using the archos as a GPS Navagation someone rings. Something should come up on the archos screen thats someone is ringing me I click answer and will put through lound speaker and mic.

Any apps out there for that?
Thanks
