I think we can really help each other out here
I have a 2007 XC90 (facelift) and have been using a modded canbus box for a while but trying to get even more out of it but my knowledge is limited, you seem clued up though so maybe you might know more and we could get something better between us? I would very much like for you to reach out directly to me either on here or on github
Firstly creating a new 2008MY for the canbus box is not the right way to go as 2007MY and 2008MY are the same, in fact all facelift XC90 from 2006-2014 all use same canbus commands so just updating the 2007MY is enough, only earlier prefacelift use different canbus address'
So got some reading for you, have a look at these threads:
https://github.com/smartgauges/canbox/issues/1
https://github.com/smartgauges/canbox/issues/11
https://github.com/smartgauges/canbox/issues/10
jesusvallejo has made some real progress and got a lot of things working that originally did not however some things are not perfect.
Also quickly would like to point out that my XC90 has been upgraded with LED daytime running lights and auto headlight switch so how my headlights function will vary from you so don't worry as much about this, if I could get mine fixed that would be great but I'm not expecting it and I just change the Dudu between day/night manually
So far what's working:
More buttons/control however these are limited - read https://github.com/smartgauges/canbox/issues/10
Open door notifications
Parking sensors
Steering geometry
Lights - read https://github.com/smartgauges/canbox/issues/11
A/C Very limited and a bit buggy - Unless jesusvallejo or someone else can help I think this will never work properly
Probably more I forgot
Hope to hear from you soon...
