Dave and Bob,

Thanks for the prompt reply.  Unfortunately, power is on, I am parked and engines are off but no indicators illuminate and nothing happens when I swtich to align.  Should "0000" appear on the IRS before the switches are moved?  It seems something may be wrong with my installation because I noticed the VOR/DME switch is not working and the numeral indicators aren't on.  I'll contact CS support for this, but has anyone else had this problem?

Thanks
