Step 1: remove HVAC control I followed spithead051's post . There are 4 white tabs in each corner, (shown in the picture below) that need to be unclipped from the top and bottom of the HVAC control unit. I used plastic trim removers  to remove the HVAC control.
1. The first thing you need to do is remove the HVAC control unit from the center console. I didn't take a picture of this but you will need one or two small screwdrivers to pry at the top and bottom to carefully work the module out. It can be tricky so be careful not to damage your dash!
Step 3: put HVAC control unit back
Step 4: attach adapter , which came with nuts and bots, to the Panavise InDash Mount . According to Amazon, the adapter  are for garmin gps, but you will need another adapter to fit the TomTom XXL gps. If you have a garmin gps, you should be done now; however, if you have a TomTom XXL or similar gps, proceed to step 5.
Step 5 (for TomTom XXL gps): I already had the TomTom adapter from my air vent mount . I did not see anything on Amazon to purchase just the TomTom adapter, but I am sure you can find that somewhere.
If you are doing the install with a TomTom XXL gps, you can connect your gps and are now done. The panavise mount  has many holes drilled for other adapters, so I am sure you can find an adapter for tablets and/or cell phones. It looks like it might also be possible to expand the mount to hold multiple devices.
I have yet to take a drive with the mount (will be doing that tomorrow), but I have tested the mount to see whether or not a passenger's legs would hit the mount. The mount with a TomTom XXL gps does leave enough room for the passenger's legs, but if you mount a tablet (I am not sure if you can, but I don't see why not), the passenger may be somewhat uncomfortable. Pictures will be posted once I get a chance.
The install was very simple and I hope this thread is useful. Thanks for reading.
