Re: Headache - Garmin 2820, Voice Com II, HF820, and Blackberry
The 2820, like the Nav III, does not include a BT microphone input/putput. Which is why it tells you to conenct a microphone to it. That's why the HF-820 is required in the first place. But it does make me wonder a bit about your configuration.
Let's start with a bit of the basics.
Have you updated your 2820 with the latest firmware? The Garmin webupdater can update the GPS firmware, bluetooth firmware, traffic firmware, voices, etc. If you haven't plugged it in to your computer and checked for updates you shoud do so now. New firmware can make a big difference.
It also just occured to me that there may be an issue with the HF-820. I just tried to look at the documentation for specifications, but couldn't find what BT stacks/protocols it supported. I sold my LT, so can't say with 100% certainty, but I'm pretty sure I had stereo support on mine.
Are you using the BMW 2.5 mm to 2.5 mm cable for the conenction between the HF-820 and the VC-II? If not, how many segments do you see on your 2.5 mm cable? If you don't have 4 seperate one then your cable does not support stereo or microphone. You need 4 connections (+ L speaker, + right speaker, + mic, - common).
