I have had this HU in my Matrix, with the Sirius Connect system from a Scion tC, for over 2 years:

I allowed my subscription to expire in August. It worked perfectly until then.

The other night I resubbed, and it was working great.

Today, The SAT button won't activate the satellite until the car warms up inside. (-9 degrees Celsius today)

It worked great before, and once things warm up, it works great.

Anyone else have this problem?
