There are ways to fit an ELM327 OBD bluetooth adapter under the access panel. I have one plugged into mine and have the panel closed.
I used this extension cord: http://www.amazon.com/gp/product/B00...ls_o05_s00_i00
If you plug that in, and unclip the OBD port from it's hole in the dash, you will have room to close the panel.
