Hi guys,
I had this problem - in exact moment when engine starter were switched on voltage in car's installation goes so low that radio goes off. Half a second later it is back on but it has to boot again and cash list of mp3 on SD card which takes almost a minute - too long.
I found a easy solution which works fine for me, I described it here
electronics engineering notes: Blaupunkt Melbourne 120 vs voltage dip during engine start If you tell me that it is not only me who has this problem than I will improve circuit and design a PCB for it. Please feel free to give some feedback to this topic. I know - it may be not that strongly related to ecodriving but I try to switch engine off when I expect that waiting for green light will take some time, when it repeats - than it becomes ecodriving related topic.
