I am searching for a bluetooth headset or speakerphone that also has a jack for using a normal wired headset. I want to attach it it a motorcycle intercom system to allow bluetooth communications from the phone to the intercom. The unit will be connected using an audio cable.

I have a Motorola HF820 that woorks fine, but shuts itself off 5 minutes or so after being turned on if their is no call activity. Tried a Supertooth, but the headset jack on the Supertooth is really a headphjone jack (no mike).

Any other ideas?
