Sl2 error meassage

I have the SL2; (stiletto 2) which was purchased 2yrs ago. about three weeks ago Sirius sent out an update which upon completion gave me an error message when I tried to connect to the satellite signal, and powered the unit down.

I have tried the following:

Spoke with customer service; nothing.

Took the battery out for 20-60 seconds; nothing

Reset system; nothing

Did a system recovery; nothing

Did a system recovery twice; nothing

Next:

I go to settings select device, choose antenna aiming; states "Press options to turn on your Satellite Radio" when I select the option it gives me an error message showing a clock and powers down.

Any suggestions? Or knowledge of third party that might be able to fix the unit?
