Hello everyone!

I recently offered to fix a relative's satnav, only to discover it's a lot trickier than I'd previously imagined!

The original problem was that it was stuck on Loading Maps. I tried the hard reset (holding down the bottom right corner), but when I was offered erase data screen, the touch screen would not allow me to select any option. Also, my computer would not recognise the satnav.

After a lot of Googling, I discovered GarminCure3 and followed the instructions given.
(I can't remember the exact order, but it involved holding the top left corner (which sent me to a calibration dot pressing screen), and eventually I managed to preboot and implement the GarminCure (with nuvi13xxand14xxseries_GCDFile__580.gcd)).

Thankfully, my computer now recognises the satnav when it is plugged in via USB and I can view it via Explorer and WebUpdater. The WebUpdater suggests I update to version 6.20 - whenever I do, it doesn't acknowledge the update once I have disconnected/reconnected the satnav and still suggests I update it.

I've also tried holding down the power button for varying amounts of time, along with battery removal. But to no avail!

I now have a satnav which turns on but just shows a black screen with GARMIN (and a blue triangle, which I assume is part of the logo), and it no longer responds to prebooting (pressing top left corner) or resetting (pressing the bottom right corner).

I have probably exhausted all online literature and am stuck for ideas! Does anyone have any ideas they'd like to share with me? I would greatly appreciate any help!

Thanks in advance :-)
