I have a F900BT fitted in an Alfa Romeo, when the electronic key is placed in the ignition the unit starts booting up in the normal way, the problem is that when I then start the car (by pressing the stop/start button) the voltage must drop as the unit cuts out then starts to boot up again. I am worried that this constant false starting may cause some problems, does anyone know how I can get around it? Thanks in advance for any help you might be able to give me.
