im not sure but Blaupunkt tend to make good stuff..

the original 1988 radio has a separate amp and I find my tape deck sounds great if I use good chrome tape and do decent recordings. the off the shelf ones are not that great quality tape usually. I like the 120 minute ones it will fit a lot more so less tape changing. the amp is up under the dash over on the drivers side, It could still be in there.

I much prefer the older non digital tuners but they are a little older. I'd prefer to tune the stations myself than have the machine do that, less buttons and it's a road distraction. one thing I dont like about the OEM one is I can;t read the buttons and it has too many unnecessaary features like programmable buttons.

right now mine seems to be on the blink, it will fade out then if I smack the side of the console and jar it it gets louder, maybe a bad capacitor or a bad wire connection in there.
