I need to install XM in GX470 ('05). The dealer cost is $595 plus tax. Is there a cheaper option that you have used? thx

What is best way for me to upgrade software on my Navigation and how can I tell what version I currently have? thx

I know this topic has been discussed many times but most of replies are dated . I was wondering what the best route to installing XM on an '05 GX. I understand it can be costly and is not a standard install but hoping systems have gotten better, cheaper and easier to install. Thx
