WM5 phone with 2 bluetooth conflicting devices

[Guest ericblz]

Hi,

Have a QTEK 8500 with T-Mobile service.

Recently purchased a Garmin 360 Bluetooth GPS. The bt allows it to act as a wireless speakerphone and actually access the phone book on the screen, very cool!

Problem is that I like to use my Bluetooth headset usually. Instead of turning the Bluetooth off and on frequently on the GPS is there a slick way of choosing between devices on the phone?

Thanks much!
