The actual GPS in the CX-3 is an order of magnitude better than on my '13 MS3. That system was a TomTom and I believe it was oriented more towards the European market, which is no big deal, but even with frequent map updates, it still had a hard time with highway updates and "iffy" addresses, which my phone handled with aplomb. I did like that it had more customizable features like backgrounds and voices (I liked the British option but opined for a French maid giving directions). So far, the new system Mazda has employed has been spot on (i.e., I don't have to pull out my phone) and I love the actual 3D renderings of buildings, especially when I go downtown and see the skyscrapers passing by on my screen. Is it perfect? By no means, but it sure is not bad.
