    I use my 8820 in my aircraft on occasion, and I have a jack on the panel to plug it into the intercom system. This worked with my old blackberry just fine, but it doesn't seem to work with the 8820. I plug in the patch cord, and the speaker on the phone keeps working, with no output to the intercom. When I plug in a regular earbud type headset, it works fine. Any ideas?

    If you look at the end of your headphone you will see the plug is different from others in it has 4 sections. This is to allow for the use of the microphone along with the stereo output. You must get an adapter to allow the BB output to work with a standard headset of input to your console. they can be obtained for about $10.00 at the crackberry store. This will solve you problem and allow it to be heard in your aircraft intercom system. Get two incase one gets lost.

    I'll try that, although this cord worked fine with my previous blackberry, and the headset plug on the handsfree headset that came with the 8820 is only a 3 connector. I don't need the stereo (my headsets are mono anyway), but I need the mike to work.

    Then I am not sure the adapter will work for you. It is used to adapt from the 8820 jack to a standard stereo plug for use with headphones. Maybe some one else with more knowledge could help with this one.

    I think that it's an impedance thing. It seems like it only switches to the headset if the impedance across the jack matches about what a speaker (or mike) should. It's funny, because my friend's iphone works, and my old blackberry worked.
