I have been a Garmin nuvi user for many years. I have no complaints with the product or the experience while driving.\nI feel, however, to play around with my iPhone's ability to navigate while driving. Because I just want to play around, I don't feel to spend any money on this little playfulness.\n\nI guess that I would like an app that uses downloaded/off-line maps, and one which closely mimics the Garmin experience – with which I have always been comfortable and satisfied. Audible directions would need to be part of the package; I rely heavily on them.\nCan I get a recommendation about which app to use? The pros and cons of the possibilities?\n\nThanks.
