Hello,

I found an other option for preventing your device to reboot wenn starting the engine:

Works in my Suzuki sx4 diesel end F710bt perfect.

Prevents reboot due to tensiondrop and ACC cut.

I have the same issue on a VW Golf IV and as much as I tried to find a solution, it never came so far. Even the technician I had placed the unit, couldn't give me any answer. Are you satisfied with this in your vehicle? What is the cost?

Hello,

The units works perfect, no more reboots.

I have found 2 options:

http://www.extremeaudio.de/gb/phonocar-5-146-spannungsreduzierer-interf-12-v-stabilisator-4sek-timer.html  (59 Euro)

http://www.extremeaudio.de/de/navlinkz-ac-pwr-st-digitaler-12v-strom-spannungsstabilisator-power-booster.html  (79 Euro)

The 59 Euro units works  and also solves the acc drop during starting the engine.

Can you tell the difference between these two? Also, is it stabilizing the power with connected amplifier on the vehicle, because the amplifier needs more power?

I had installed the Phonocar 5/146 and now the Pioneer doesn't restart.

I discovered that my F920BT worked perfectly and didn't restart when I started the car.

It never had updated the firmware, but today I updated the firmware to the latest version (2.00300) published by Pioneer.

My surprise was that after the firmware update my AVIC F520BT restarts when I turn on my car.

How can I do a downgrade to know if the error is the firmware ????

Has someone had the same error ????

Thanks.
