Garmin Nuvi 54 Help

Hi all, longtime lurker but first post, I need some help from you lovely people. I have a Garmin Nuvi 54 EU that refuses to boot properly and only will when a USB cable is connected when it does it displays a weird image (see video) any advice on this?

Also unable to get the computer to recognise it and therefore currently have not succeeded to update it either.

Thanks Jordan

That looks like a hardware problem to me, I doubt it's fixable.

Thats a shame ohwell shall send back to Garmin as still under warranty

Thought I would keep you up to date on this sent of to garmin for a replacement
