In my collection I have a HH (7digits and pinsound) a BH with US backglasses (7digits) a MARS (Ready to migrate to 7 digits) and of course i'm looking for a SPIRIT.
For we have planned to add voice as we have done with HH. (SC-01 + code added).
MARS and BH have double backglass and i love this, next step ... VOLCANO ? Maybe, but storage is limited ...
Enjoy HH !!!
