I have a garmin etrex summit that says ADC fail Unit needs service. What does ADC mean and how would I go about getting it fixed? What do you expect it would cost?

Hello,

The Garmin Etrex Summit does not have the ability to add maps to it.

2 possible reasons.
Either memory is full.
Try remove all data from history, and have a small run.
It should be OK then on PC upload.

If not OK, only hard reset can cleanup device, and return to factory settings.
Consult your manual for hard reset instructions.

Check out the Garmin owners manual (page 59):

This SHOULD get you on track again!
Hope this is helpful

Hi,
I have a Etrex Legend (same size as yours) that no longer works - It has a good lcd cover.

absolutely! Hve yoiu checked that this model does not have a switch on the rear as well as on the front? the one of the front is standby. The other one is main power. Not 100% sure about your model so just check first. Other than that take it back to seller for replacement or instructions

The unit needs to have the screen facing up. The unit will not read if it is vertical. Garmin cust serv finally helped me with that one. Once you turn on the unit, it could take up to 20 minutes (usually about 3) to grab satelites.

You will need to input the security code for the maps. If you purchased them through Garmin or a Garmin dealer, contact Garmin and they will give you the security code.

see discussion at http://californication.mtbguru.com/2005/11/20/deconstructing-the-garmin-etrex-vista/ Its possible that there's a bad connection at the ribbon cable, but most likely its a bad connection at the edge of the LCD glass panel. I've had two eTrex fail because of this problem. Don't pay the riduculous price Garmin asks for repair - just buy a new Magellan unit. If you must get a Garmin, go with the high-sensitivity receiver.
