Q: I have a fourth-generation 20 GB iPod that I use in my car with a Dock Connector that was installed to share the satellite input. I’d like to replace it with a larger capacity iPod but I don’t want to lose the ability to use the Dock Connector which did not work with my first-generation iPhone and will not work with an iPhone 4S. Is there an adapter I can use with a current generation iPod classic? Or what is the latest generation iPod…
