I'm from germany and me and my wife we bought us in 2008 the Avic HD3 - Z2 is the US version.
After years we thougt in december that we need an map-update...so i found a drive at eBay that has the maps from 2010 and a puts the Software from HD3 to HD3 II (Z3)
Delivered from California it reached me one month later...i replaced the drive, the Unit made some updates and everything was fine...until today.
When the Unit starts it only shows Starting up Pioneer and after 5mins I think you can see the Navgate picture but nothing else happens...
On my trip through the internet I found this site and with the instruction I flashed the firmware from disc of the US Z3
The first time i entered the Test Mode on the right Side there was Platform Version 3000200 but after flashing the fw of the Pioneer Website it Shows me 3000100 and the Start up freezing still resists.
Now I think its like iPhone jailbreaking - you cant go backwards to an older fw?! Is this right?
But I don't know how to fix the problem...and how i get the right fw.
And why it doesnt boot we only used it and now its cheap scrap!
Please please help me
And sorry for my bad english, i did my best
