It is not mine Nuvi...
I didnt fix the display ribbon cable till now. I connected new battery and made a connection via USB cable to the PC but Nuvi doesnt make any sound (display is detached) neither PC gives any sign of USB device presence. It seems that the Nuvi is fully dead. Reseting button does not make help. Too bad...
Waiting for repairing display cable (i am waiting the kapton tape from DX..)...
