Question about Lowrance Iway 500c GPS Receiver

1 Answer

SCREEN ORIENTATION FLIPPING

After the unit has been on for a while it sometimes flips between the screen orientations.(north up/travel direction up/3-D). When it does this the screen may go blank for a split second before the next view appears. the unit does not lose location/tracking when this happens. I have been unable to duplicate this using a power converter in the house - it only happens when driving. I have made trips of several hundred miles without it happening and made trips of less than 100 miles with it happening continually.

I have recalibrated the screen to no avail.

    I wish there was a fix because mine has been doing this for a while. Drives me nuts. Sometimes I just reboot it and that works. Sometimes it doesn't work.

    Yesterday, I left it on in the house and when it heated up, it started doing it. So it is probably a temperature related problem. I use mine on my motorcycle also and come to think about it, it never does it on the bike. Air blowing on it keeps it cool.

    I too talked to lowrance and they said for only $250.00 you will get a brand new one. I already paid them $600.00+ for the 500c. Im not giving them any more money.

I have the same problem, it started after updating. Spoke with Lowrance tech and said it is a hard drive problem.
I had to purchase a 600 for $250 because they gave me a discount for having paid for the update and the unit
is malfunctioning. They refused to consider that it may be a software problem. The screen loses calibration and
the unit goes balistic with the orientation. Have had the unit for 4 years with no problem until updates were installed

Looking for the garmin you speak to you dont have to type in the address you say it.also has a flip screen


Hello,

None of the Garmin units will have flip screens, unless your referring to Dual Orientation. The nuvi 3790 and 2360 will have dual orientation screens they also do speech recognition so you will be able to speak commands instead of manually inputting them.

Hope this helps!

Quest 2 antenna contacts cleaning???


You will need a small phillips head screwdriver. Turn the GPS unit over on its face with the back and flip up antenna facing you. There are 6 screws on the back holding the two halves of the GPS together. With the Quest oriented so the hinge of the antenna is away from you, carefully remove the two phillips screws on the right hand side of the back of the unit. This holds an endcap of the unit and the flip up antenna in place. Be VERY careful in removing this, as the antenna has a small spring putting tension on it and this spring will easily pop out and get lost. The antenna should easily come out at this point. If you look carefully, on the left side of the antenna, you will see the swivel for the connection. There is a spray called DeOxit used by radio repair people that does an excellent job of cleaning contacts. If that is not available, use a Q-tip and some isopropyl alcohol and gently clean the contact areas of the antenna and where it plugs in on the chassis. Allow the alcohol to dry or gently blow it out with air. Reassemble, (don't forget the spring), and it should work just fine.

Walking figure has morphed into a three sided blob that seems to point in the direction of travel.


On the map screen, hit the "enter button" then hit "enter" again while highlighting the "orient Map ahead." This will change back to the walking figure. The triangle that you see, only shows when you orient the map northward. Try using both ways to see which you prefer.

Hi!
Please go into the menu and select the 'Nav' tab then choose the 'Chart Orientation' setting and set to 'North - Up', also make sure 'North Reference' is set to 'True'.
If that doesn't work, reset the sounder back to factory defaults and try again.
Here's the manual to you sounder:

Furuno Radar Model 1833C


You have two things that orient the radar, on is called heading (or bearing) alignment. This is where you aim your radar so that a target comes up at 12 o'clock when dead ahead. Access this mode by pressing and holding menu duing power on, and go in to Installation Mode, radar setup, next page, align heading. I have posted a "tip" on this, search for VX2 radar alignment.
After this is done, North up is accomplished by having a magnetic input (fluxgate compass or autopilot). Calibration of this compass varies, but if it is accurate, then all should line up nicely.

Nautilus problems


Hello:

I also have the Nautilus & the processor just isn't as fast as the newer units. You can adjust the track up mode to only refresh when the rotation of the map is over a cert amount, degrees, (resloution angle) if you have it set to a low value it will continually keep the route dead up & constantly refresh.

See section 4.3 Map orientation in the manual.

On the route reversal are you getting the pop up screen that alerts you that the route has been reversed?

I assume you have a manual?

I am actually contemplating selling my unit as I have a Garmin 478 from work & the screen is much easier to read in the bright sunlight. I had my Sitex on my Grady which had a bimini, but my Mako CC does not & the sunlight washes it out.

I'm thinking $375 for the whole unit with a wide area chart of MA.

Orientation


It is not likely that there is a software error that could cause that problem so I'm going to cover some basic information first. Forgive me if I'm covering stuff you already know. There are 3 chart orientation modes, North Up, Heads Up, and Course Up. North Up you already know! In Heads Up mode, the chart will only orient heads up when the boat is moving. Unless you have an electronic compass interfaced to your GPS it has no way of knowing which way you are facing. Once you start to move, it compares your new position to the old position to determine which way is heads up. If you are not moving, the map defaults to North Up even if you are in heads up mode. Course Up mode is commonly mistaken for Heads Up. In Course Up mode, the GPS orients the top of the screen toward a waypoint that you have told the GPS to go to. If no waypoint is selected, the GPS will default to North Up orientation. So I guess what I'm saying is, make sure the boat is moving, and make sure you're not in course up mode (unless you want to be).

In the unlikely event that there is a software error causing this problem, it can easily be fixed by getting an update from Standard Horizon. You can either get them to send you an update chip, or download it online and copy it to a blank C Map card. When you turn the GPS there will be a message on the opening screen that identifies you software version. Get that information before you call Standard.
