XM suddenly stops working on 2010 Prius V, Package AT

Hello,
I've found an odd state (and fortunately, an interim solution) to an odd problem with the factory XM radio installed in the new Prius.

The problem seems to manifest itself when the signal is fluttering (going back and forth between reception and no reception, where the automatic mute kicks in to eliminate the white noise when there's no signal.) This seems to happen most frequently in parking garages where one end is open and has some weak signal reception and others where it is dead.

In one place where I park, it fades intermittently very quickly in a very small space. The net-net is that when this occurs, the signal seems to go into a permanent mute, even when the problem goes away. The only way I've found to clear it is to go somewhere, park, power down the vehicle, and power it back up...

Thought I would pass along...

I had the same issue with the XM in my '08 Highlander Hybrid, and would fix it the same way. Haven't had the problem with the Prius yet.

I think you will have MANY owners of a wide assortment of vehicle Makes & Models who are encountering this very problem.

We have an 07 Acura RDX, and it exhibits a similar problem, and requires the same fix (ignition OFF, wait a few seconds, and ignition back ON again).

Since it seems to affect a varying number of Makes & Models, I suspect it's something in the XM
portion of the radio.

Once someone Posts a resolution to this problem, you may have inadvertently aided MANY owners of MANY varying vehicles with this same problem!

Thanks for This Post
