Hello & Welcome,
Please try the following procedure:
If the eTrex is not responding correctly, for example it is not receiving a satellite signal, it may be necessary to perform a master reset. This can also be used if you want to restore the factory default settings. To reset the device please follow these steps:
Please be aware that a master reset will erase all waypoints or favorites and will restore your device to the default factory settings.
Please let me know what happens.
Can you tell me what type of batteries you are using?
When you replaced them, did you carefully check the contacts at each end of the batteries to see if there was any "dirt" there?
It sounds like you are loosing power to the unit, that is why I ask.
Are the batteries that you have "new" (full power)?
I would check those contacts and clean them with alcohol and a lint-free cloth, if you have one.
Also, I don't understand "the screen gets a lot off line" - does that mean that is show that a lot of the satellites are not being detected yet?
If the unit is New - less than a year old, then yes, I would return it for warranty repair (to garmin).
If it is less than a month old, I would take it back to the store where you got it.
Can you tell me how old it is?
If that is the case, I would return the unit to Garmin so that they can repair or replace it under the 1 year warranty which comes with ALL of their GPS units.
The procedure to do that starts with contacting Garmin so that you can get a Return Material Authorization (RMA) number. Here is the rest of the information.
Call or e-mail a Garmin Technical Support Specialist to describe the problem and request a return material authorization (RMA) number. You will need to provide the unit's serial number (if applicable), your return shipping address and a daytime phone number.
Phone:1-800-800-1020 or(NNN) NNN-NNNNbr />Fax:(NNN) NNN-NNNN/p>
Once you have received the RMA number, you also will be told what dock number to include in the shipping address. Ship the unit (insured) to the following address and include the assigned dock number:
Garmin International1200 E. 151st StreetRMA Number: (insert your RMA number here)Dock Door (insert the dock number here)Olathe, KS 66062 USA
