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.

My new Lowrance Hook-5 GPS isn't working, I'm a noob, how do I get this function working?

'isn't working' is such a broad problem. If it is only the GPS, it is covered from Page 49 of the manual and shows you can access Satellite information. Note, it almost certainly won't work in your garage or storage. It need to see the sky as the antennae is internal.

The unit has an installation guide. In my personal opinion, it is better to let a professional boat engineer install it, mainly for the correct fitting of the transducer on the stern. Correct placing makes all the difference to a good set up, unless you intend to fish without the engine running.

All they need is mounting, power through a fuse direct to the battery, and the transducer fitting. Then you put the boat in the water and switch it on.

Just got it. Plugged in and connected wires to 12v battery. Held light/power button 5 secs. Wont start

First, just press and release the power button, you don't have to hold it in.
second, is your battery fully charged?
third, red wire to positive terminal, black wire to negative.
These are obvious things to check, but sometimes the simplest answer is the solution.
Did you install the fuse holder included with the unit? If so dI'd you put in the 3 amp fuse?
If none of these things work, call lowrance. I work in retail and have experienced taking brand new units out of the box and upon hooking them to power discover they were dead. Defective straight from the factory.
Good luck.

Lowrance 350 wont turn on

Plug it in. Is there a green or red light on the iWay 350? If red, it will probably turn on now while plugged in and just needs to be charged. If it won't charge, it is malfunctioning. If no lights come on when plugged in, the 350 is malfunctioning.

Does the green light come on the cigarette lighter adapter? If not, the fuse in the cig adapter is blown or the power cable needs to be replaced.

Installing the Lowrance HDS 5

You do not need the data cable connected unles you are hooking it up to other electronics, ie computer, second GPS sounder ect. You only need to conect the red to the positive on the battery and the black to the negative.
