Congratulations on your new Crosstour
My 2011 CT EX-L is undergoing a sound system upgrade at this very moment.
I'm keeping the factory radio and navigation, back up camera and diagnostics display, but upgrading the amplification and speakers.
I asked for pictures to be taken during the install, I hope to post them after I pick up the car.
I am also planning to update the alternator to a high output model.
Then we'll see about paint accents.
There aren't any engine mods that I am aware of except cosmetic options.
Hello and welcome to the club! Congrats on your Crosstour, show it to us when you can. There are lots of great choices for parts, services, and many owners willing to help you. Safe driving and happy modding!
