Tw auto updating maps
Assuming that the unit does what you want it to, then you either update the map one time for (per your post) or you get a lifetime update (lifetime of that unit).
You can get lifetime updates from Amazon for a good price. You can update the firmware of your 750 at no cost.
We’ve also updated our color scheme and added new icons to help you quickly identify exactly what kind of point of interest you’re looking at.
Places like a cafe, church, museum or hospital will have a designated color and icon, so that it’s easy to find that type of destination on the map.
If one manually deletes all foreign languages and foreign voices, then it can just barely fit.
Another option is to buy a Sandisk SD card and place the maps on the SD card.

I have used it for a few 30 mile local trips and it seems to work well including audible red light camera warnings.Back to the original poster's questions: Putting the latest Garmin map on a 750 is not easy.The 750 does not have enough internal memory for the latest map.Howard Another option is to buy a Sandisk SD card and place the maps on the SD card.
Howard Use Garmin's website to do a comparison of the features found on each unit.Keep in mind that with a bit of patience, you could find and buy a new nuvi with Lifetime maps for under 0.) Should you decide to update the map, please let us know before you start because there are things you should do before trying the map update. It may be worth the sixty-odd dollars for a Lifetime update. Garmin does release firmware updates for discontinued GPS models.
