My cycling computers "down" sidebutton has worn through due to my bad habit of only skipping through data pages using the lower of the two buttons. Rubber has perforated and it fell off during a ride, so I don't have anything to glue back in...
It still works but it is a near to a safety risk trying to press the inner mechanics during a ride. I'm aware that in most scenarios I could still scroll the other way or even re-arrange screens to accommodate for it, but is there a way to fix this, has anybody a good idea how or has even done a similar repair? It's also not ideal that the IP protection is voided and the next wet ride could end my beloved Edge after over 4 years of partnership. Yeah, I'm a keeper.
Garmin doesn't officially sell replacement parts, only cases (which wouldn't help to actuate the button internals), I've only seen one or two used parts on Ebay, but located in the US and I'm in the EU, so shipping costs would probably be higher than the part's price.
(I'm aware that this is only remotely cycling-related but perhaps somebody had the same issue since the buttons inherently wear on use on any kind of similar device).
After getting some useful responses on parts on the internet, I shied away from dirty glue jobs. The whole back of the device can be found (with and without battery) on various internet portals, mostly shipping from the East but a defect or used full Edge 520 unit might also be suitable, considering that a new 540 costs over 300€.
In my case, 25€ (which is less than 1/10 of a new 540), so it was worth the money because I'm still fine with battery life and features of the 2016 model and that probably keeps it alive for another two or three years, hopefully.
Here's what I came up with
- From inside the case, I covered the hole with tape
- The new button is the tailpiece of a zip-tie, glued onto the tape
- The ugly part: As protection and to give everything a more rubberish feel, I just covered the hole with Pattex glue which never full hardens out
It kind of works, probably not forever but at least temporary until the replacement case arrives from China, probably not until August.
