I have talked with other 2011 Durango owners about the Sirius radio signal being jammed/signal lost by cell phone antenna in all parts of El Paso Texas. It didn't happen with my 09 RAM 1500, nor does it happen in other cars and trucks.

Is this problem only here in El Paso?

 

Ours will consistently drop the signal for 2 seconds at a time in two separate places. No overhead obstructions.
