AVIC Z120 upgraded to Z140 no GPS


Recommended Posts

I have a Z120 that I upgraded to Z130 software. I then upgraded to Z140 - when I first upgraded it didn't recognize my location and my speed, direction, turning was just way off. Now, it doesn't even recognize the GPS being plugged in / no signal. Any ideas?

 

Shitty first post, thanks in advance.

Bump? Still no GPS -

 

I'll note that I upgraded from Z130 (legit Pioneer Software) to Z140 (Ebay Software) when I lost GPS functionality.

 

Is there anyway to use my old Pioneer SD card to downgrade my software?? When I put the old SD card in for Z130 nothing happens.

 

Thanks!

Just to clarify, my post was to try to solve your GPS issue, not to reload an old version. SO a cold reset didn't fix your GPS problem?   If not, you might want to try to force a re-initialization of the head-umit. I've done it a few times. Unfortunately I can't tell you exactly how. I went into TestMode and deleted \USER\SETUP (after making a backup).  Then rebooted and the HU rebuilt the setup - just like the first time I powered-up the new unit.

 

I suspect there is some way of forcing it to load from SD, but I don't know how. I am suspicious of that Ebay software. Did it come with a unique serial number and require a registration key? If not it is bootleg with some kind of hack. It takes a lot of nerve to sell stolen software on Ebay. Definitely against Ebay policy. Maybe you should contact them to get your money back. And if it is legit, you should be able to contact Pioneer for help.
