98 Boxter stereo question
 

I just purchased a 98 Boxster (really sweet deal) but the dealership where I purchased it (not a Porsche dealership) had let the battery drain and when they replaced it, the stereo is inoperable. I read the manual and have the code, but the unit itself seems to not be getting any power. I re-read the manual about 5 time and understand how to put in the code, but is there something special I should be doing to get power to this unit (aside from pressing the power on button)?

Thanks in advance for any assistance, and this thing is a SCREAM to drive........
