Well I took the deep dive, without consulting this forum, and did the Pioneer upgrade to my AVIC-X910BT after backing up.

Looks like they must have added something to the "Boot Partition" so I thought I can just restore and be working as before... Not the case.

My Software bypass no longer works,So I took the following steps:

1. Erase all files on the flash Drive

2. copy all backup files to the flash drive

3. restarted the unit

4. If Park Brake is not engaged I cannot make setting changes

Does the hardware By Pass still work? I don't want to pull my Radio if it will be a waste of time. Any help will be appreciated (I am using Diafitia combined changes)

Does the hardware By Pass still work?

Yes. Testmode still works as well so you should be able to perform the soft bypass as well.

Can you share the Software By Pass, It's been a while and I am not sure where notes are.

Its all on this forum.

Thanks vBlue42, I did find the posts,

I edited the Pioneer.ini set ParkBrake to 128 then to 256 and restarted, It does not fix the issue, I suspect Pioneer added something to the Boot Partition.

I'll keep playing as it was working yesterday before the upgrade.

The soft bypass works just fine with

3.02.

Bet my ground came lose... I'll check that.
