Hello, friend. Name’s Arthur. I have this old Garmin Etrex H GPS device (the yellow one) and it looks very similar to your Etrex Vista H, but it has no stick button. The disassembling method suited just fine here, so I thank you Sir for this tutorial. I was trying to disassembly my Garmin because I am having a problem with its display. There’s a vertical line that its not displaying, so I decided to take a look. However, there was something strange. The display contacts were not locked by a connector, but by something like a durex tape. Seemed very precarious. Have you ever disassembled this yellow Etrex H model? Any ideas on how to solve my problem?

I forgot to remove battery for years and the battery chamber got damaged. So chamber was cleaned and repaired but now I cannot on it.

My gps often says low battery when the battery is fine.

It just shuts off after a while of saying ‘low battery’.

How can I fix this?

Perhaps I need to take it apart and clean something to do with the battery connection?

I did once have a small battery leak but it all looked good…. did not see any damage.
