If what they need to see is the serial # on the radio, then by all means, I'd recommend you remove the radio yourself, rather than pay for them to do it. It isn't chalenging to do at all.

It basically consists of removing the ashtray/cupholder assembly, armrest and center console. This gives you access to the bolt that hold the radio and the small plastic cubbyhole in place within the dashboard.

All that's required is a medium size Phillips screwdriver, a reasonable amount of care and about 15 to 20 minutes.
