I really can't get to pre-boot on my nuvi 67LM. Pressing the battery for 5-6 seconds, then plugging in the device, it appears in Updater, i press OK, it starts, but disconnects right away, then i get the error message:
App: Updater

OS: WIN32 Windows Platform, Major Version: 6, Minor Version: 2
Processor: Pentium Pro or Pentium II, RAM: 2097151 KB
IOU_USBLINK.CPP-710-2.8
I tried all the methods described for nuvi devices but it does not work, anybody knows how to enter pre-boot mode on nuvi 67LM (do i have to downgrade the firmware or anything else?)
I can't use unlocked maps...
Many thanks!
