Sent an email asking eclipse sales on the true story about the avn5495 getting the software upgrade for Sirius and here is there response:
Because of the different software used on the AVN5495, it requires different software for the Sirius tuner. We will have a software update for the AVN5495 in July (about 90 days) that will allow the unit to recognize and operate the Sirius tuner.

This software will be made available to all of our retailers by the end of July. No charge for the software update




Thanks,



Eclipse Sales
