Does any one know of a reasonable way to get a line input into the factory audio/komand system? I am totally lost after searching.

The Gateway 500 seems the best option I have found for an Ipod/Iphone

If anyone has any other links, I am interested before I purchase a link for my iphone for ML350 with Command.

 

Cost and where to buy???

 

if you just want an audio line-in, there's an aux input in the globebox.

if you have an ipod/iphone, the factory ipod option is attractive, but pricey. the installation instructions can be found here online to save some cost.
