My build in navigation (NV1) in my Mazda mx-5 has gone in a loop. When powered up you first see a picture of a chip (see enclosed) after a while the picture is added with a red cross (like the chip is missing). I do not have a built in phone, I connect it with Bluetooth. It is not possible to restart or switch off the unit.
Can I do a total reset and read again on SD card? Regards Leif
