I haven't done this replacement yet, however, i was thinking to this solution if i replace the DVD/GPS for the OEM headunit MID:

I would like to keep the MID in glove box, connecting the original MID harness to an longer extension harness and keep the MID in glove box or hidding somewhere (underseat!?)
