Hi everyone,

Just last week I bought my first car, a 94 R33 GTS-4, but the guy sold it to me without a head unit in it. So I went and bought a new one and when I was putting it in, I noticed this little green box thats in the picture. Can anyone tell me what it is and what it does? I managed to wire everything up and it's all working perfectly, but I just found it strange that this thing is sitting there doing nothing. I don't know a thing about car stereos, so I'm sorry if this is a really dumb question

Thanks for your anwsers so far! I just thought i'd mention that the cord for the aerial comes out from behind the glove box and then splits into 2. 1 end goes into the back of my head unit and the other half goes into this box. So I assume that it is actually doing nothing at all because it isn't really connected to anything. Does that make sense?

Is it powered via that red cable? I guess the other option is an antenna BOOSTER, rather than a range expander.

Someone may have run a TV screen kinda HU seperately and needed better tv reception.

My reception (radio) is pretty aweful most of the time. =-[

    • Agree with Rob. I recently did mine and replacing with a brand new unit made the most sense compared with rebuilding my existing gearbox.
    • Are you suggesting that the kit did a cheap and nasty job of just jamming the wheel in between other things and caused the misalignment? I mean, we normally do this with an integrated crank trigger wheel, not something bodged on. It's not 1995 any more.
    • I mean, given the number of BMWs you own their tolerance for improper torque is rather low. The number of torque + angle spec bolts and non-reusable bolts in one is nuts.
    • Atmospheric vent requires something that doesn't use a MAF for load. You would need a standalone ECU for that.
    • Hey all,   I’ve got an RB25 with a trigger kit that includes a crank wheel, and I’ve hit a wall trying to sort a timing belt tracking issue. The belt either rides right on the edge of the cam/crank pulleys or walks slightly forward once the engine starts. It tracks okay-ish for a moment, then creeps right to the edge—and honestly, it’s stressing me out.   I’ve spent hours removing and reinstalling the belt, double-checking everything:   Tensioner setup is good, checked multiple times Idler pulley and washers are all in the correct places Followed the RB25 timing procedure step-by-step     The only thing I changed was the rear crank washer—I swapped the OEM one for a Neato version, and it made things worse. The belt now sits even more forward than before. I’m beginning to think the crank trigger wheel itself (from the trigger kit) is the issue—poor design or slightly off dimensions.   What’s strange is that with the previous belt setup, it actually ran fine for a couple of years—around 4,000 to 5,000 miles, even with hard driving and high RPMs. But even then, the belt was always riding right on the edge, and I know that’s not ideal or safe long term.   At this point, I’m debating whether to:   Machine a few mm off the crank trigger wheel to bring it back in line, or Replace it entirely with a better-designed unit     Only thing is, I already have the Cherry Hall sensors, bracket, etc.—I just want to replace the wheel only, not the entire kit. Anyone know a brand or supplier that sells just the crank trigger wheel on its own?   Would really appreciate any feedback—especially from anyone who’s run into this exact issue and found a reliable fix.   Thanks in advance.
