Thread: Satnav no longer gets recognised by computer

Hi, so basically I have a Nuvi 2597LMT but I can't update the map. It still charges and can be used, I just have to find another map and copy it to sd card. I'm guessing its a hardware issue with the mini usb port? My old nuvi still connects to the laptop just fine.
I've wiped and reset the faulty nuvi and reinstalled garmin express, but it still doesn't get recognised. Is this common? And has someone else been able to fix this issue themselves or would it have to be repaired by a professional? Hoping it's a fix I can attempt myself.
