So you still cannot access the unit in Mass Storage Mode when you connect it to the PC? If it's still not accessable, it seems there's a problem that the cure fw can't help with. Could be hardware related, in which case probably not worth a repair charge for such an old gps anyway. Or you have a corrupted NV memory, and without an NV backup you need expert help. Maybe someone with an NV dump from another 205W could help but there needs to be changes made to it to reflect your unit's identity. You will get an offer by PM if anyone here can help with that, as it's not to be done in public. ;)
