I have a 2009 TSX with Navi and the buttons on the steering wheel don't respond and the previous owner took it to the dealer and they said they would need to charge $1200 for a new module.

I pulled the panel down under the glove box to remove the unit and noticed the label is different than some of the modules on ebay.

Mine is
REV. 04 with S/W REV: 10.07.000

I found one listed on Ebay that is listed as brand new but is:
REV. 03 with S/W REV: 01.03.000 and the new one has a date 01/07/2016 printed on it as well

On ebay I've seen
REV. 02 with S/W REV: 01.01.000
REV. 01 with S/W REV: 01.07.000
REV. 01 with S/W REV: 01.03.000
REV. 05 with S/W REV: 11.00.000

I assume I would want the one with the highest number as it should be the most up to date but the one with the date on it had a lower revision number.

Anyone have any advice/input about this?

 

I found this which is for 2011 and up http://techinfo.honda.com/rjanisis/pubs/SB/B12-021.pdf

I would get the newest rev as some older ones had issue.
