Can you go in preboot mode ?
1. Power OFF your Nuvi.
2. Press and keep holding the most right upper corner of the LCD screen
3. Power ON your Nuvi but DON NOT release your finger either from Power button nor from LCD screen (keep both pressed until the procedure ends)
4. Nuvi will boot in Pre-Boot mode.
I move your post to the proper section

As you said "I cannot Switch it on
I cannot switch it off"
1). What did you do before ? ( - flashed with original firmware or modified firmware )
2).How about Nuvi battery power level before flashing?
3).In case of modified firmware - Did you flash with the same hwid boot.bin ?
4).Did you try to slide power botton for at least 20 seconds ?
5)....
