need your advice !!
I have a built-in D-net in the car, but unfortunately no nav.
I chose the Nokia 6600.
About T-Com and the Navigate II I therefore have a full-fledged navigator in the car. Since I also open my vehicles, I simply take the mobile phone and the GPS mouse with me and therefore have a GPS everywhere.
Even on the mopped, it works fine.

Now, my actual "threat":
I want my phone to be placed in sight. Isn't there something for the ventilation grids or to push on the side of the radio shaft ?? Don't want to hang such a sucker in the front window.
But it doesn't have to be a luxury version of Agate.
Look forward to your suggestions.
