Hi there, I got a European Unit 700bt.
After using it since about 7 months with no mods, but regular pioneer.eu upgrades, the system started flashing the many times.
I went to the settings area and figured out that the brightness was running up and down itself.
Its like a lamp, which ist flashing, because its almost death.
So, I contacted pioneer Germany but they didnt know the problem and sent me instead to a service point where they deleted my software and set it up again for new.
As a result it was working for a few minutes and it restarted flashing again after a few kilometre
