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
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.
