Thorpedo

Does anyone know whether the Blaupunkt Reno SQR 46 or the Reno 2 was included as Option 158 with a February 1990 911? My COA just states "Reno", but it seems like some of the 1990 911s came with the Reno 2. I am debating returning to the original type of radio, Porsche Classic or just keep the current block-off plate. If it helps, my car also had option 494 - the Blaupunkt amplifier.

Any help would be appreciated. Thanks

My cab was assembled in March 1990 and it originally came with a Reno 2 radio.
