does the Sprint Booster void the BMW warranty?
I don't think anyone's had a problem with it yet, if you want to CYA you can always uninstall when going to the dealer - it's apparently less tha 5 mins install, and uninstall. Easy, and the dealer will never know. Most members here leave it on and never had a problem
