XM Source not displayed

Question

I purchased an Alpine IVA-W205 unit with XM connectivity. It worked fine for a few weeks then without warning the XM is no longer displayed in the source menu to be selected. I checked with XM and my account is OK. I can't get the demo channel even. I don't even have the ability to select XM. It's like it never existed. Spoke to retailer and they said they have experienced this with newer Alpine units and it is a software issue that Alpine says there currently is NO FIX ?? HELP !!!!
