Hello Elchgemeinde! I need your help! I would like to experience your experience with later built-in navigation devices! My previous, loyal companion “Petra-, (so we called ours, “old lady, Becker Traffic Pro 4720”), has said goodbye forever. They don’t release the CDs any more. So I have to buy something new. My favorites are so far: Becker TP 7945 Bluatooth (should be a super device but unfortunately no color screen) I was so happy with Becker seeeeeeehhhhhrrrrrr. Pioneer AVIC-X1 (software from Teleatlas should not be so good?) Already a great thing with extendable screen, TMC, DVD navigation, etc. Maybe someone of you has already had experience with these devices. Could one ever install an RTI, or something comparable aftertaste? Greet Barna
