Then, unfortunately, after all you've tried it's likely there is a hardware fault and unless it's obvious and fixable when you pull the unit apart you may as well leave it in parts for spares. Sorry i can't suggest anything further for you to try. Maybe others have ideas ....

Yes I try in the car also. At the beging of my trouble I try it first in the car for more than an hour, becouse it has no power at all.
Did you leave the GPS with a flat battery for a long time ?
Did this GPS ever work properly in your hands ?
Maybe you could try to convert to 34xx (Nothing to lose really)!
You could also try to flash some very very old 37xx firmware !

Yes. This is the thing that I will do - flash to nuvi 3490, but before that will flash with old firmware. Can you give me link to an old version please?
No, this device I bought from ebay.co.uk and never work in my hands.
And what you mean flat battery?
Thank you for the advise.

Flat battery means dead battery.
We bought 2 devices from ebay and the both were with dead battery, but only this can't connect with satellites.
The first thing that I did was to open the device disconnect the battery for about 1 hour, look over the antenna module, soldering the connections and after that I look for help.
Thank you.
p.s.
Now I flash with ver.3.60 with cure, but I can`t find ver 3.90 for original. Can I flash with ver.4.80 for original??
