Becker 1432 Aux In or Out?

[kwontumspeed]

So after 15 years I finally pulled the 1432 due to faceplate issues, really just the volume button. The first thing I noticed when I slid the stereo out were two coax plugs on the back. After popping the top, it looks like it’s certainly input or output. I’m guessing it’s input since there’s only two. Looks too homemade for it to Becker work, maybe not? Anyone have a Becker with the aux option and does it look like this?

Also, I’ve taken the faceplate completely apart and am repairing a series of plastic parts and springs which have snapped or worn out. I’ve never done this before but can say that as long as you’re paying attention to what you do, a faceplate repair is doable. I’ll report back when it’s all put together

Somebody put those plugs on the back in order to inject signal on pin 9 of the pair of LM1877Ns (for the cassette module) on the board.

Thanks. So this is the aux in, but tape has to be inserted mod?

Not sure ..... just try it!

Yep, aux in is activated when tape is inserted. Inserted a tape then killed the motor so mechanism doesn't spin the tape nor does it eject it when car is turned off (or power button is hit). Now all I need is a bluetooth adapter, splitter so I can still retain the aux in, and all systems go after that.

The MBT-RX is a good one. It is very reliable --- I use it on my other car that is also equipped with a (slightly more modern) Becker.
