I only see one eprom chip on the face of the main nboard (not face board) with four pins on either side. It is near the right front with "bottom side up" close to a plug. The number is 56585 TBDK.
There are two eproms on the very right edge one after the other; both 8 pin; one (second on back) is straight 8 the other(first to the front) looks staggered 8 both in upright orientation; They are backed up with the heat sink plate. Neither of them say 9355093. I did originally look at both of these eproms; removed the sink and looked for numbers; they were visible but no 9355093. I returned them w/ white contact grease.
The center is ARJ International
snip... "prevents the unit from being turned on via 12 volt ignition."
So how would one turn on the radio? The tech will call me Monday with a quote on a few other items. I will confirm it must operate correctly. He told me he burns the new chip and I might see the CAL ERROR(?) momentarily on start. Should I have him just remove altogether and not replace? NO burn..

The security 9355093 chip is the one located closest to the front edge of the board. The writing may not be seeable on the chip. In fact, it is printed so faintly in some cases, it may appear to not be printed on at all. I believe this was for identity protection purposes on Delphi's part, however, instead of hiding the chip, they made it stick out like a sore thumb. Remember that this Eeprom is located on the main board only and not the faceplate.
I hope this clarifies this for you.
By the way, what is this service ceter you sent yours to? Just wondering for reference. Also, take note, with the eeprom installed/replaced, it prevents the unit from being turned on via 12 volt ignition.
Thank you,
Starflare5.
