Back in the day, I used to work for a large electronics chain, in service. Blaupunkts were not a brand we were authorized to service, but we'd occasionally see them anyway for repairs or install. My recollection was that they had a great reputation, but they were also kind of unusual as far as install, use, and repair.
My only experience using one was in a Vauxhall in the UK. It functioned, but it didn't strike me as intuitive.
I managed to get a radio, amp, speakers and subs into my car, and found it was still hard to hear anything. It's still there, but disconnected.
I guess if you're going to have a radio in your Pantera, a Blaupunkt would be as "cool" as any. But personally I wouldn't bother. I found that I prefer the 351C symphony instead.
You may find that that radio needs a bit of internal cleaning of the potentiometers and tuning gang (I assume it may have one), and perhaps some caps may be dried out and need R&R. I'm no expert on Blaupunkts, but it looks a bit long in the tooth.
