Question about GPS
In order to protect the markups of local resellers Lowrance have built into its US versions of its HDS GPS/Sounder units a "Geo Fence" that monitors where the unit is. Units built with US base maps (identical to worldwide versions except they have a more detailed map of north America and cost literally half the price) will deactivate metric units, all languages except English and continuously flash up on the screen a warning "this unit is not for use in your area. please contact your local reseller"
You have obviously purchased a unit that is made for only the USA and so far there is yet to be a fix for the problem of geo fencing.
it is written into the "firmware" that is programmable components, that need "code" to be written to and changed, it is fairly common in the computer/electronics industry, now how true that is I dont really know, but it is not a simple software driven thing, firmware (as the name implies) is the layer between hardware and software. Supposedly the units "knows" via hard coded data where it is and where it is supposed to be, and as soon as an update is downloaded, or an OS unit is started up in Australia it throws a wobbly and has a whinge big time.
What's interesting about this is that international units do not have this issue, hence you could purchase one for your yacht and travel around the world.
So my advice will be for you to purchase an international version of the gps so you can use it in any part of the world.

The Lowrance hds 7 sold in the US is purported to be worldwide, but isn't. Users outside the US are having problems with the geofencing. Have heard that you need to send your unit back and trade it in on a worldwide unit.
It could be that Lowrance has come up with a software update. You could check with support on www.lowrance.com to see what they have. Maybe a new card would do it.
I hope this helps. If it does, I'd appreciate a 4 thumbs up. Thanks,

The Geofenced part of the HDS is in the small circuit board with memory IC on it. If you replace that board with a non geofenced board the hole unit will work fine. The question is how to get a non-fenced board? Lowrance has the "bad" behavor of not service US units in Europe. I.e. not recommended brand for oversea sailing....

An acquaintance purchased a Lowrance HDS-7M from the
states and was concerned with GEOFENCING as the first I had heard of it.
Firstly he poke to someone at the Boat show and they didn't seem to know too much about it.
Then rang Lowrance Australia, and they informed me that it was going to happen, but hadn't happened yet.( A natural response for someone who is trying to protect their market.)
he then decided to email Lowrance USA with the following questions:
A) Has GEOFENCING been implemented on units currently built and purchased in the US.
(B )Will my unit work to it's full potential here in Australia,
This was there response:
"The feature you refer to is not currently available in the products we produce. However, research, development and design, is an ongoing process. We here at Lowrance are always interested in the needs of our customers and we really appreciate your suggestions. It helps to illustrate the path the company needs to follow to better serve our customers by producing the types of products you desire. You can always log onto our website www.lowrance.com for news about new features, updates, and products.
Once again thank you for your input and Thank you for supporting Lowrance."
He's only used the unit a couple of times, as it is the middle of winter, but all seems to fine at the moment.
Our gut feel is that, they are tinkering with the idea, but weather it happens or not is anyone's guess. I think at present you are safe to buy from the US, but doesn't hurt to ask the reseller some questions before you buy.
But IF you DO have one that is Geofenced, then i believe, one cannot "Crack" or take it off, defeat, or otherwise modify it. As it's an inbuilt part of the software's core coding, i maybe wrong but i think this is how it is?
