Two queries, not really problems (undoubtedly to be answered by Colin!) CD based V3 satnav, GS.
1) If I don't put in a destination, and drive home, at a random point it will start directing me home. But not every tiime. How does it know where I'm going, and why does it start at a random point, and then only sometimes?
2) JUST before I reach one of two destinations, one being my home, the other my mother's home, the system will give three pairs of short beeps. Always at exactly the same point (I guess about 0.5 miles from the destination). BUT it ONLY does that with those two destinations and no others ever. It will do it even if I haven't put a destination in but am in fact going home or to me old mum's, ie am running without guidance.
Just curious if anyone else has experienced these things, or has any ideas as to why?
