Google maps oddly enough has even giving me issues. Not even an ios7 thing...had issues with it in ios6 too. Screen goes to sleep at some point and then when I wake it up it doesn't resume navigation....and then it's not just a matter of hitting continue...I have to start a new navigation from my now current location...massive hassle while in a moving vehicle. I don't use navigation that often to warrant not using apples version I just sincerely hope they fix this by the time gm is released.
