478 USB repair help needed

 

I was told on facebook that

I was told on facebook that maybe cleaning it with contact cleaner and then using dielectric grease may save it. Son I just bought some. I'll let you know if it works.

I need it working soon because I need to load the routes for this upcoming ride.

Good luck

Welcome to The Factory.

Good luck. If your cleaning fails, you may want to check with sharcnet for a potential repair:

I doubt that a very quick repair would be possible by anyone via mail order. I wonder if a place like Batteries Plus might be able to help.

Have you confirmed the problem is with the USB socket; i.e., have you tried a different USB cable in case it turns out that the problem is with the cable rather than the GPS MAP 478's socket?

Wow

Wow.. that's a mess!
If it were me & the contact cleaner & dielectric grease didn't help..
I'd get a maginfier, a good pair of needle nose pliers or better yet a locking hemostat, and find a small BRASS bristled brush .. pluck out a brass bristle & gently try to push it in & out of each contact. The bristle needs to fit without a huge amount of force.

Aside from that, spray the begeebus out of the male cable with the contact cleaner and plug it in & out a bunch of times. Blow it dry, and smear the dielectric on the male cable, plug it in, and cross your fingers.

Probably want to keep it bone dry next time, eh? grin

edit- thinking about it more- before you try cleaning the sockets with a brass bristle, maybe try a plastic bristle from a toothbrush or one of those thingies that hold your new socks together, or tag on clothes.

Corroded USB Port

I'm an electronics tech by trade. No amount of cleaning is going to fix this. You need to replace the usb port which is a relatively simple task for someone trained in doing so.

For a quick repair, take it to a local cell phone repair shop. They should be able to replace the port within a few minutes (15).

Repairs of this kind are relatively inexpensive or at least should be. Just find a repair depot that has a good reputation.
