In a similar situation. Just purchased a home with a Niles GXR2 system installed back in 2008. It sounds great and works pretty well. I was thinking of purchasing a IM-NET card off of eBay. Slightly concerned that Pandora doesn't appear to work...has anyone gotten this work?
Also, I would like to be running the latest firmware on the cards and main unit. However, the ICS site doesn't appear to have these. Does anyone know where I can get hold of the latest firmware?
