Dear Users!

I have two GPS navigation, what contain originally theese:
HW: 2521A MSB2521 GPS Rev2.1
DDR 128Mb, 4Gb Flash

But, my first one is not find GPS signal, and the other one have an empty white free screen.

(Maybe NAVON n670+ ?! Nothing on it)

If anybody have a firmware, please share with me.

Thank you

ps.: if i write to wrong topic, sorry... please move to the correct one..
