We would be happy to offer it cheaper but have not found a way to do
it. The best one would be to have higher quantities, but that needs someone
who can fund a new GTA0x project upfront. Here we are simply limited
by the number of plastic cases and uses GTA02 devices that are not yet

well, that can be repaired.

We still have some replacement batteries or a Nokia BL-6C works.

Regarding batteries there is not much difference - Nokia is no longer
producing them. But there might be replacements around for a longer

The latest Neo900 schematics includes a switch which disables the GPS
antenna under CPU control. So you can be sure that no GPS signals
