Updating Maps Nuvi 750

When you purchase a new unit, Garmin allows you one free update within 90 days of first acquiring satellites. When you purchase an old unit, you are not entitled to any updates for free.

Assuming that the unit does what you want it to, then you either update the map one time for $40 (per your post) or you get a lifetime update (lifetime of that unit).

You can get lifetime updates from Amazon for a good price. I just looked and find one for $65

You can update the firmware of your 750 at no cost. Install WebUpdater on your computer, connect the 750 with a USB cable, and run WebUpdater to update firmware, voices and other updates:

Map updates (City Navigator North America NT), however, are a different story. Except for new nuvis that may be entitled to one free map update, Garmin requires either a numaps OneTime map update (probably not worth the expense) or a numaps Lifetime purchase (about $60 or so which will entitle you to up to four map updates per year for the life of the unit--you will need to decide if this is worth it. Keep in mind that with a bit of patience, you could find and buy a new nuvi with Lifetime maps for under $100.)

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.

The 750 is a very good unit. It is the same as my 760. Due to a good combination of features, these units are better than most later nuvis, especially the inexpensive ones. It may be worth the sixty-odd dollars for a Lifetime update. Remember that the lithium-ion battery in this unit probably will need replacement in the future. Again, this can be done and doesn't cost much.

Caution: do not update the nuvi 750's firmware. The latest version is buggy - and since the 750 is discontinued there will never be another newer firmware version.

Hmm, what problem exists in Firmware 5.30? The reports I see state that it works well.

Also, 5.30 was released a very long time after the model was discontinued. Garmin does release firmware updates for discontinued GPS models.

I had very bad experiences with 4.9 and read about problems with 5.1 which was pulled.

I had not noticed version 5.3

Will give it a try.

I have had so many problems trying any new firmware from Garmin for the discontinued 750 that I concluded that Garmin's software group does not own any 750 units anymore.

So, the new firmware probably never gets tested at all except by the owners.

But, I will give the 5.3 a try.

I guess I spoke too soon:

I wonder why 5.3 was pulled.

Well, one week ago, on May 14, 2012 I installed the latest firmware 5.3 on both of my nuvi 750 units.

It retained my favorites, seems to work properly. I have used it for a few 30 mile local trips and it seems to work well including audible red light camera warnings.

Now, I hear the firmware has been pulled from the Garmin website.

Not sure to stay on firmware 5.3 or to install an older version.

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.

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 noticed that Amazon has a Garmin model 50 (lower end of the new 2012 line) with lifetime maps for under $130.

I don't think it is wise to invest any money into map updates for a 750. I think this Model 50 has more modern features like junction view and is a better option that paying for lifetime maps for a 750.

Use Garmin's website to do a comparison of the features found on each unit. This will allow you to make a decision that's partially based on how you use the unit and the features available against the thought of purchasing an SD card to hold the later map editions vice a unit that has an increased internal memory.

The 3 digit Nuvi units ending in 0 will display the name of upcoming cross streets in the banner bar which is not present for any other unit. I'd almost gladly downgrade my 885 for an 880 just to regain this feature.

Amazon.com also has the 4.3 inch version for $110 with lifetime maps.

One can buy lifetime maps for the 750 plus buy an SD card, but for a little more money one can get a new unit with a new battery, warranty, faster cpu, better screen, with better features like junction view.

http://www.amazon.com/Garmin-n%C3%BCvi-5-Inch-Portable-Navig...

Model 40 costs $100 (4.3 inch screen)
Model 40LM with lifetime maps $110 (4.3 inch screen)
Model 50LM with lifetime maps $127 (5.0 inch screen).

I like my 750, it does the job. However, I wouldn't spend money improving it. I think the money is better spent on a new unit.
