Voice control

Is it possible to use voice control on a tomtom ONE (v3)

Of course, just use a suitable Navcore.
But before it works you have install a micrphone, change the ciruit board a bit and reprogram the micro controller.
Sometime I wonder why people want voice control on a device without a mic....

I thought maybe someone has tried to use a bleutooth headset or something like that.....
Some people always try to find the limits.

Even if some of the oldies offer BT it is only used for data transfer, so still no chance ;)
