I am looking at leasing a new car and the cost for the built-in OEM Navigation/GPS is crazy expensive, especially for a vehicle I do not own. The monthly payment will be significantly less if I do not get the Navigation. I know in "the old days" all of my cars did not have Navigation/GPS and I survived. Plus, the Navigation apps on my iPhone do a great job, but the screen is small in comparison. Curious if anyone has recently opted NOT to get GPS in their new car and rely ONLY on their phone for Navigation? Do you regret it?
