Not acquiring position - Lowrance iFINDER H2O C Plus GPS Receiver

Same for me very often.
I think this is due to starting a road without waiting long enough that sattelites are acquired.

In fact 3 sattellites allow to compute position, 4 are necessary to compute position plus altitude.

Accuracy of position and altitude is much better from 5 sattellites acquired.

So I advise to start your device OUTDOORS, in an open place (not near walls as it masks sattellites) and wait until screen automatically moves to run mode, meaning enough sattellites are acquired.
You will get better chances to have a good accuracy.

Also on Garmin connect site, when you load your ride, you can correct altitudes automatically using real maps.

If a device is used daily it should be able to acquire satellites in a minute or less. Using a GPS device while it is outdoors with a clear view of the entire sky is the ideal condition for acquiring satellites. Please know that there can be several different factors that may cause a GPS unit to not acquire satellites:

• If your unit is trying to acquire satellites for the first time, it may take longer than normal to establish an initial position. If the unit is powered on and outdoors with a clear view of the sky this should not take more than 3-5 minutes.
• If your unit has not been used for an extended period of time (more then a month), it may take 3-5 minutes to acquire satellites.
• If your unit is indoors, it may not acquire satellites. Even standing next to a window indoors will block a majority of the sky which is needed for a device to locate and lock onto a satellite signal.
• If you have just finished updating the software in your unit or you have performed a master reset, your unit may take 3-5 minutes to acquire while outdoors as the data that is used to locate satellites may have been erased.
• If your unit has traveled over 500 miles while turned off or not tracking your travel, it may take 3-5 minutes to acquire even in ideal conditions.
• If your vehicle has a protective coating on its windshield or electronic devices which interfere with the unit receiving signal, your unit may need an external antenna* in order to acquire satellites.
• If you suspect this to be an issue, try taking the unit outside of the vehicle with a clear view of the sky for 3-5 minutes so that the unit can acquire satellites. If your unit loses satellites once moved back into your vehicle you will most likely need an external antenna*.

If your unit is still having trouble acquiring satellites, please ensure that it has the latest version of operating software by using our WebUpdater program. Once your unit is updated please allow the unit to acquire satellites outdoors in a stationary position with a clear view of the sky.
*Note: Some units may not be compatible with an external antenna. Please check the Products tab on the external antenna's page to see if your unit is listed.

are you inside when trying this ? Garmin has a very bad reputation in acquiring satelites when in coverered position.
Go outside and you will notice it goes much faster.

Question: Why won't my unit acquire satellites?
--> Answer: There are a several different factors that can cause a GPS unit to not acquire satellites:

• If your unit is indoors, it may not acquire satellites.
• If your unit is trying to acquire satellites for the first time, it is normal for it to take a while to establish its initial position.
• If you have just finished updating the software in your unit or you have performed a master reset, your unit may take longer than normal to acquire.
• If your unit has traveled a long distance while turned off or not tracking your travel, it may take a longer period of time to acquire.
• If your unit has not been used for an extended period of time, it may take a longer period of time to acquire.
• If your vehicle has a protective coating on its windshield or electronic devices which interfere with the unit receiving signal, you may need an external antenna.

If your unit is not acquiring satellites, it is recommended that you place the unit in a stationary position where it has a clear view of the sky. In some cases it may be necessary to take the unit outside of your vehicle as certain vehicles inhibit the unit from acquiring satellites. As the unit receives signal from the satellites, it will begin to lock on to them individually until it has acquired enough information to establish your position.

If your unit is still having trouble acquiring satellites, please ensure that it has the latest version of operating software. You can do this using our WebUpdater program which can be found at the following link:

You need to go outside and turn on the Garmin until it has acquired a satellite lock (15-20 minutes). Kansas is the default location (Garmin Headquarters). Once you have acquire satellites, the Garmin will remember the last position as the starting position when the power is turned off. You know you have acquire a satellite lock once "Ready to Navigate" appears on the top of the screen.
