I have had my street pilot 3 for 11 months and love it. I would plug my cell phone ear bud for voice prompts. Last week it stopped working along with the 5 other earpieces I tried.....figured it was the gps. Sent it to garmin, said it was fine. Has anyone had this problem or know of an earpiece that works "better" with the sp3. Thanks, Mark. Ps the new tech board is great.
