I have an 07 Vec SRi and I'm looking to change the BID to a GID as I hate the horrid pixelated screen, I have found a GID but its from an 03 and isn't paired to a headunit so it sounds ideal but I'm unsure whether its compatible due to being half can?

Whether this will make a difference or not... I'm probably going to fit an aftermarket double din touch screen H/U at some point in the future...

I have used the search button quite a bit but not finding the info required.
