So close yet so far....

Hello all --

I have a 2000 9-3.  I built HW version 5.5 and am trying to use SW 4.1.  It seems I keep getting a little closer to having a working device, but cannot reach the finish line.
- Couldn't load the bootloader.  Eventually killed my 328P but replaced it with one from a Nano (that already had a bootloader installed).  Could be the old version 328P bootloader.  Don't know if that could be causing the next set of issues.
- Loaded the 4.1 software via IDE.  Serial monitor was stuck at "Configuring RN52..."
- Bridged GPIO7 and ground, which got me to "RN52 Configuration Completed!"

Where I'm at now:
-Plugging in board to any power source (CDC connector, USB, ISP) gets a solid red power LED
-Plugging into USB gets me a brief flash of the Rx and Tx LEDs, then nothing more.
-Plugging into the car gets me a dim flickering of CAN1 LED, nothing from CAN2
-I have never seen any activity from the blue or red LEDs at any stage in the build.

My car came with a CDC and I also retrofitted a NAV system from a 2005 9-5.  Those items work correctly together.  Replacing my CDC with the Bluesaab is the same result as simply unplugging the CDC.

I've checked for solder bridges numerous times. I have the correct voltages at all of the places on the board and on the chips I can find to check.  I'm just out of ideas!  Some new ideas on where to check would be great.  Also, I believe I saw reference to one of the prominent project participants being located in the San Francisco Bay Area.  If you read this, would you be willing to take a look at my board if I mail it to you?

Thanks in advance!
