My AVIC firmware 1.90 EUR, latest bluetooth.

I've a real trouble. My AVIC is restarting when I drive my X-Trail with 40km/h or more. It's stable in parking - everything works fine, but if I drive AVIC F900BT restarts as soon as find GPS coordinates and speed passes 40-45 km/h.

I've checked connection and test voltage on the pink-wire. No problem found

What's up?

I've read on the forum, that I've to send it for upgrading to PIONEER. Is that only way to solve the problem????

May be that's a problem with Gyro-Sensor?

1.9 is the only upgrade available.

have you done any mods to the firmware?

You can confirm whether or not its GPS related by unplugging the GPS and going for a spin; its possible that for some reason you're loosing voltage on the YELLOW or RED wires (constant and accessory voltage)

might want to try with the VSS wire unhooked as well

edit: thanks for correcting me boris

900 and 90 DO have gyro and speed sensor.

1.9 is the only upgrade available.

have you done any mods to the firmware?

No mods. But I've tried to repair original files from "working" ROM from other AVIC. I've tried to use test-mode. Anyway it worked in the same way, restarting after passing 40-45 km/h.

I've disconnected GPS antenna - all is OK! Works fine - no restarts, but (as it would be) couldn't receive GPS coordinates.

I've tried to connect/disconnect pink wire to the AVIC. No results... Speed sensor works fine, i'd checked it with the voltmeter in motion.

No other ideas?

wow thats really messed up

I'm going to say its gonna have to go back to Pioneer, give them a ringy and see what they suggest
