I replaced the radio/nav system in out '11, no problem with radio/nav operation.
The only problem I had was on a trip to Florida, the Sirius cut out and message to contact Sirius. I called and they stated that the subscription ran out, but that was impossible, just renewed the month before, then it hit me..............different radio, different subscription. Gave them the radio number and good to go.
Dealing with the same issue right now. Had some pressure damage happen during a install and I found a few good ones in eBay! Do you have Navi or infinity system? You have to get the right one or else it won’t work.
