I currently have the Concert II (single disc) and was wondering if it's possible for me to upgrade to the 6 dics double din unit like on other A4 models? Because my climate control has this tray thing under it, will it be fine to set the climate control lower and install in the 6 disc or even a Nav double din?

Any help is always appreciated..thanks.

 

will im not much help in how to do the project, seeing that i have only downgraded from a six disk to a single disc...but my stock bose six disk is for sale if you are interested...
