Took it to the closest mazda dealer near my house, and I've been informed that "it might be a problem with the CMU" - I couldn't quite get a good explanation as to what the CMU is, but from what I gather it's the electronic unit that runs the nav system? Now I have to wait for Mazda to authorize a replacement.
MZD units are usually very reliable. There's an update around for some of them. Might be worth asking if yours would be revived by applying it. Did you buy the car because you needed some of the MZD functions and are now finding life difficult with the unit not working? If so, send me a PM.
