I have an N2, with the most recent version of the iPod adapter installed. I agree, the interface is crap. I would actually prefer to just control the iPod direct if this is all I am left with. The iPod will not work as designed unless you have a N3. You will also get the full function of the XM receiver. There is a service listed on eBay, that will upgrade to an N3, which involves hardware upgrades. I have searched the site here, and generally see that it would be difficult for a novice electrician to make the upgrades, let alone one would need a parts list, etc. I have emailed the guy on eBay
