The process discussed here and on some other older threads worked just fine (thanks!). Here are the steps to update as best I can recreate them from memory:
1. On the Jensen unit, open the tiny slot on the top right corner and remove the microSD card. It is very small, 15 mm x 11 mm. IMMEDIATELY place the card into a sealed envelope so you don't lose it. (You will need a micro to standard SD card adapter - see below - so if you have one, go ahead and place it into the adapter.)
3. Make note of your Jensen model number from the unit or from your manual. You will need this during the process.
2. Go to naviextras.com and create an account. You can use the site as a "Guest" but before getting the update you will need an account so go ahead and create one. I believe during this process it will ask you to ID the unit for which you are registering.
3. You will receive an email verification to test the email address you gave them. click on the link to verify your email address. You will be taken to a page that confirms your registration.
4. Return to the naviextras.com home page and if not already logged in, then log in.
5. On the left side, click on "Maps and More"
6. On the Maps page, look for the "Free Updates" tab and select it.
7. You will see the line, "f you have not installed the Naviextras Toolbox yet, please download it from
here." Click on "here" and install the software.
8. At the end of the software load process, be sure the "launch now" box is checked. (Otherwise launch the program from your Start menu (Windows PC).
9. You will see at the top of the screen "No device is connected" and you will get a screen that says "Please connect your navigation device!"
10. Insert the microSD card into a standard SD card converter. They look like this:
http://www.amazon.com/SanDisk-microS.../dp/B0047WZOOO Hopefully you have one for a camera or some other device in your home. Otherwise you can get one at Microcenter, Best Buy, Target, etc. Insert the SD card into your computer SD card slot. (If you don't have one, you will have to get a SD card to USB port adapter, or else do this operation on someone's computer who does have one.)
11. Here's where it gets a bit hairy, but don't worry. You will get a message saying to "disconnect" your system (the SD card) or else if you proceed your system may be corrupted! You can try disconnecting (removing the SD card) and reconnecting a couple more tries but it didn't work for me. Instead, click "Ignore" and proceed.
12. The software immediately prompts you to run a backup of your system before making any changes. Don't skip this step! (It may say it will take a few hours but on a modern computer should only take 5-10 mins.)
13. After the backup is done, there will be a screen saying something awkward to the effect "system fixes are needed." Go ahead and click this, and this will run the update for you. Don't worry as the screen runs through file after file after file. These are the maps being updated.
13. When done, you can close the software and remove your card. (The technically correct way to remove your card is to right click on the storage device icon in the taskbar tray (or else open Windows Explorer and right click on the storage device listed under "Computer") and select "Eject" - you can then safely remove the SD card.
14. Remove the microSD card from the standard SD card converter and immediately either place it into your unit or place it again in a sealed envelope until you do, so you don't lose it.
Was that on dial-up, DSL or cable modem? I'm running an Apple computer so I have to do my update on the local library's public computer. I don't think they'll let me use their computer for 4 hours!
