Scott, I do not have the catalog numbers as I purchased the items at the local store. The dongle does have the smaller plug thus requiring an adapter also available from Radio shack. Both my dongle and Bluetooth headset are manufactured by JABRA. -----Original Message----- From: gps-talkusers-bounce@xxxxxxxxxxxxx [mailto:gps-talkusers-bounce@xxxxxxxxxxxxx] On Behalf Of Scott Marshall Sent: Sunday, October 08, 2006 11:02 AM To: gps-talkusers@xxxxxxxxxxxxx Subject: [gps-talkusers] Bluetooth ear piece and dongle Hi: Sorry I don't remember the answer to this question. Someone here recently purchased a Bluetooth headphone and dongle from radio shack and is using it with the BN. Do you have the catalog numbers? Does the dongle plug directly fit the 1/8 inch jack on the BN or is an adapter required? Thanks The dongle mentioned on the Sendero cool products page seems to require an adapter. Scott
