Was finally successful in getting map updates so thanks for the heads up Grayhawk51. Opened the Naviextras toolbox and immediately had to update the toolbox. Plugged in the micro SD card, clicked and clacked around a bit and when I poked the update button it proceeded to update all states, Canada, and Puerto Rico to include maps, buildings (3D), and POIs. Now at least I can use the Jensen GPS for a backup when the Garmin decides to lunch out. The screen for the Jensen is still just a bit too far out of my line-of-site to use comfortably (that counts for the backup and side camera views also). So I'll keep using the Garmin but it's always nice to have a backup that's up to date.

The Jensen unit comes with a "Latest map guarantee". The way it works is if you register the map with iGo at the website within 90 days of the first use, you can (if there is one) download the latest update for free..
You need to remove the SD card from the unit.
Go to www.naviextras.com and register.
Now download the update program for free, it is called "Naviextras toolbox"
Install toolbox on your computer. This is a map maintenance program, it allows you to do things like update, make backups of you map, and access add-on's like more poi or other things.
Now place the micro SD card into your reader (you will need an adapter or reader if you do not have one).
Start the tool box program and log in.
Down at the bottom left corner you will see it working, when you connect it will check your map for it's version, registration, etc.

***If you get the message that says the map was not shut down correctly just ignore it. This does not apply to this unit.****

Once this is done click on the UPDATES button.
Any updates that are available will be loaded on your map card for free if it is within the first 3 months of use.
Now you can click on Maps and there you can buy maps too, but there is no reason too.

If you want to watch a walk through you can see one at www.naviextras.com, look at the bottom right corner of the page and there is a link to instructions.

One thing I noticed was that the date in the registration will show 2013 or 2014, this is actually the registration/copy-write date, not your map update date. You have to click through the settings to licenses to see the actual map version you have.

The igo map also will use POI from other websites, I have added red light cameras and speed traps to mine from a 3rd party. It really isn't a bad map program but it is different from Garmin.

You can also download manuals from jensenaudio.com¬*-¬*jensenaudio Resources and Information., look for the VX7020, this is a very similar radio. This radio actually comes from ASA which is a division that sells the Jensen branded products. You can find manuals and service here: ASA Electronics

I hope this helps. I tried to remember all the steps and hope I didn't miss something. Also ALWAYS backup your map, if something goes wrong you have to order a new Map SD card from ASA if you do not have it saved.

And for me there is a second positive... They do not convert the Canadian Greyhawk dashboards to Kilometers. My GPS has a speedometer that I can set the units on so I don't have to squint at the little greyed out numbers below the miles per hour.
Purchased an RV GPS from Camping World. Works great, free updates for life. Automatically changes from Miles to Kilometers when crossing the border. I like it alot ! I got mine this summer for 249.00 I see it is now 329.00.

I have a Jensen in my 2015 Greyhawk 31FK. I find the Jensen GPS useless because in the daylight, the screen gets washed out and you can't see it from the driver seat. Still using my Garmin.

Can the Jensen head unit's overall firmware/software be updated?
Currently between RV's, and it might stay that way !

After three trips and a total of maybe 1200 miles, I've decided to go without the Jensen nav system. My best solution so far is my iPhone using the Apple Maps software (I also have Google Maps but now that Apple has fixed most if not all the maps problems from the initial release, I like it better both for the graphics themselves and for the voice directions.) Both of those apps are also updated constantly, so there's no issue with loading update maps into a gps system. Frankly not sure why anyone would buy a GPS-only system any longer if he owns a smartphone.

SD card is located right below the volume knob on the front of the unit.

I wouldn't depend on it either. I still use my Garmin. The micro SD is hidden right below the power button.
