My computer won't recognize my nuvi 760 in order to upgrade maps

Hello

you need to update your map

Purchase your map updates (if necessary). You can purchase map updates for your Garmin Nuvi from the Garmin website. There are two basic options: a lifetime purchase or a one-time upgrade. The lifetime purchase gives you access to any new updates for the life of your device, while the one-time upgrade will provide you with the latest current maps, but you'll need to purchase again if you want to upgrade again later.

Make sure to log in with your myGarmin account before purchasing the map upgrade.

Connect your Garmin Nuvi to your computer via USB cable.

Open the "myGarmin" website and sign in with your Garmin account. Make sure to sign in with the account that you've purchased the map updates on.

Click the "myMaps" tab on the myGamrin dashboard. This will load a list of all of your purchased map upgrades.

Click the drop-down menu in the "Recent Map Purchases" section. Select your Garmin Nuvi from the list of devices.

Install the Garmin Communicator Plugin when prompted. This is required in order for the Garmin website to transfer the map files to your Gamrin software on your computer.

Download and install Garmin Express. This is the program that allows your computer to interact with your Garmin Nuvi.

Register your device in Garmin Express. If you haven't already registered your device, you'll be prompted to when you start Garmin Express. You'll need to register in order to update the maps.

Click the "Updates" tab in Garmin Express. This will show all of the available updates for your Nuvi, including the new map update you just purchased.

Click the "Show Details" option next to your Map Update. Click the "Install" button that appears. You will need to accept the agreement before the update installs.

Wait for the maps to download and install. Once you agree to the terms, the map update will begin downloading to Garmin Express, and will then be transferred to your Nuvi. This will likely take several minutes to complete.

unplug the Nuvi when the update is complete. The Nuvi will reboot and begin installing the updated software on the device. This may take another couple of minutes.

Garmin Express Garmin Express but it probably won't be free. $50 for one time or $90 for lifetime... dont get the lifetime, get a new unit instead.

The problem is probably with touchscreen (a thin film on screen)

You can try order a replacement touchscreen on ebay and replace it yourself
Tip: order a couple of them, they are cheap but extremely fragile

You need to plug in your Nuvi into your computer, once connected go to www.MyGarmin.com

It will then seek your Nuvi model and ask if you like to update maps or update firmware.

I would update firmware first.

Love my Nuvi 760

GPS City (http://www.gpscity.ca ) sells compatible Inland lake maps. Please note Garmin does not recommend them for that unit but I am sitting at my desk with one in my Nuvi 760 and it is working fine. You will need to turn off the street maps first to see the inland lake maps. I tested it with a Garmin Pre-programmed card for Alberta Canada.

User's manual available at www.garmin.com. Select "support", then "Manuals". Enter "mobile electronics"+"automotive"+"model #". Manual says that selecting a language with a person's name will speak street names.

tools.settings.map.map info

it is in the box it came with, on the back of the instruction book.
If you did not buy it 'new in the box', you will have to refer to the 'activation' code sent to you email.
The Garmin Nuvi 760 does not require SD card maps if you are using it in the US, btw...

Does the Garmin Nuvi 760 require an additional memory card for normal use?

The simple answer is : no it does not need and SD card to work

Won't download updated free maps.
