music in car? Or more guages??
I second the glove box solution. Not only have I never met anyone who actually uses it to store gloves, how many folks acutlly use it for anything. You could mount the unit under the dash plate or mabe a swing-out solution on the door. If you really want to get fancy you can even make a little clip to hold the registration for the nice police officer. Please keep us posted as to your solution.
