I have been toying with the idea of taking 3-4 weeks off and going on a cross country road trip with my 2010 Audi A4. I am still in the early planning phase but wanted to reach out to the oppo community for some advice and pointers. The map above is my potential route but we’ll get into that in another post.
With that said, I wanted to know from you guys what would you consider good road trip gadgets to have.

-Give me a pic/link and reason. This could be anything ranging from a standard GPS unit to a really good smartphone dock for the car.

-I also want to know at what point will I need to start worrying about load on my car with all these electronics connected.

Lets just keep on gadgets for now I plan to ask for other things like pre/post-maintenance, best roads/attractions to a particular destination in a followup post.

Thanks for all the advice!
