Opening up case of Garmin Edge 520

Has anyone opened up a Garmin Edge 520 and can explain how it's done?

Need to get inside mine to repair the USB connector, but the 520 doesn't have screws holding it together like previous models of the Edge series did.

Suspect it's glued together and some heat and a bit of prising will get it apart, but thought I'd ask here in case someone's done it before and knows the trick

OK, I sorted this out myself in the end. The glass screen on the front is held down with double-sided adhesive. If you VERY carefully prise around the edge of the screen using something thin enough to get in between the case and the screen (those blue plastic things you get with an iPhone repair kit are ideal, but I used a scalpel blade and lots of care), you can gradually lift the screen off the case.

As expected, the USB connector had some corrosion on it at PCB level, and a bit of IPA and a tooth brush got rid of that, and now I can get it talking to my PC again!

I had to scrape off all the old double sided tape from both the inside face of the screen (use something soft like a plastic scrape or your fingernail here, otherwise you'll remove the black screen background) and the inside of the housing, then put some new double sided tape down and voila - its as good as new!

Not sure how watertight my double-sided adhesive job is, but time will tell

Hi Ian,

The whole screen assembly would probably need replacing in your case, as the glass front seems to be part of the whole screen assembly.

I put up an instruction that details how I pulled it all apart : https://ifixit-guide-pdfs.s3.amazonaws.c...

You can see some photos of the disassembled unit there

Cheers,

Mike
