Thread: Nuvi 50LM Europe not connecting to GE or seen by computer

You already have the latest firmware (SW V4.00) and even if it was an older version loaded you actually don't have a firmware problem. So, re-loading it via sd card won't help either because corrupt fw really doesn't manifest in any of the symptoms you're seeing. Most likely it's the first possibility you mentioned, i.e. a hardware issue. If you want to confirm that, here's a flash kit to re-load V4.00 via card: (NOTE: Bad file removed - See Post #4)
There's unlikely to be any change after, but at least it will eliminate fw as the cause from your thoughts and you can concentrate on maybe fixing a hardware fault. Read Butter's post #9 [Only registered and activated users can see links. ] for troubleshooting and possible repairs for a flaky USB socket.

I will try the flash kit you gave me and report back. I have already looked at the physical connection and it looked ok. As a precaution though I have already done as Butters suggested, and re-flowed all the connections and supporting legs and cleaned everything with IPA solvent. All looks good from that part anyway.

Update. The fw flash did not work. The nuvi turned on, said loading maps, and went on to the operating screen. No mention of updating or loading message on the screen. I know the sd slot works as it reads my personal poi file ok from there.
The ldr bin in the flash kit did not contain any information, is this this correct ?
