When I took the 2820 out of the box and tried it out, it would display incoming caller # and Ignore or Answer boxes. Performed the web update, and now I can't answer...the only box displayed is "hangup". I thought it might have had a problem with the update, so I loaded it again, and same thing. I can still make a call just fine, just can't answer incoming ones. The GPS recognizes my phone, correct model...HELP! BTW, top of the GPS window says "dialing" instead of incoming.
