I know there are tons of threads on this topic, but not are really complete and conclusive.

There are several solutions to adding iPod connectivity to the G37. iSimple, GROM, Spec USA are the ones I know of.

A shorter list of Bluetooth adapters.

Can anyone who has had experience with either/or comment on the pros and cons of their setup?

I really want to have steering wheel controls for both the bluetooth and iPod. I'd also like to have a caller ID on the stock monitor (show who's calling) as well as song/track info.

Thanks
