I just replaced my "BAD" PCM with a newer used PCM. It works great, however, as I was programming I noticed a descrepancy in the firmware. This is what I have:

SW VERSION 4.0

UNIT PCM
TARGET 05395BD1 / 4505
ACTUAL 05395BD1 / 4506
ENTERED YES
FOUND YES

UNIT SYSTEM SOFTWARE
TARGET 05462AD1 / 4605
ACTUAL 05462AD1 / 4605
ENTERED YES
FOUND YES

UNIT AMPLIFIER
TARGET 00017600 / 3105
ACTUAL 00017500 / 3504
ENTERED YES
FOUND YES

UNIT NAVIGATION SYSTEM
TARGET /
ACTUAL 00179412 / 5004
ENTERED YES
FOUND YES


My old Nav disk is
Part # 997.642.257.02
Date:04.2005

My new Nav Disk is
Part# 997.642.257.05
Date: 05.2007


If I put this new disk in will it update correctly or do I need some other disk for the Amplifier??

Any good help is appreciated.

Thanks!

Steve

 

I may have found my answer.

1.) I think the disk will work
2.) I need Dealer to attach PIWIS to upgrade Amplifier firmware

 

how do you imagine connection between nav disk version and amplifier soft version???
