MK5 Golf GTI

Hi guys, I've already posted this on the on the Briskoda forum but didn't get any answers, and as my Octavia vRS's head unit is similar enough the the one in the MK5 golf gti, I thought someone might be able to help me here.
Long story short I had the standard Skoda Stream HU but wanted to get aux (and a few more watts for the stock speakers) so I upgraded to a used 2007+ Skoda Stream MP3 HU (very similar to the MK5 one) that came with an 3.5mm aux CD changer emulator adapter for €30.
Here are the problems I ran into:
1. Guy who sold me the radio didn't know the antitheft code, payed a sketchy website €9 for the code and it worked.
2. At first the AUX/Radio had no bass whatsoever. The next morning it spontaneously started working.
3. I decided I wanted to add the CD changer too but to the original AUX cable I bought. I installed the 3 aux pins based on the wiring diagram on top of the radio into the factory 12 pin. The CD changer and Radio worked, but the AUX only could from the left side of the car, extremely quiet and no bass.
4. I really wanted the aux to work again so I plugged the emulator cable back in. The AUX worked, but was very quiet, little bass and grainy, but this time sound came from both sides of the car.
5. After hours of messing with the grounding cables of the emulator and cursing at the bloody thing I didn't fix the AUX, only making it even quieter and more grainy when adding extra grounding. I replaced the original CD changer 12 pin without the aux AND NOW THE CD CHANGER DOESN'T WORK ANYMORE. Only the radio does.
I'm really annoyed with the whole thing but I don't want to spend €100+ upgrading the HU just for a 3.5mm aux. I have one of those cheap bluetooth FM transmitter things that works but the sound quality is average.
I'd appreciate any advice :happy2:

Fixed it, it was the entire harness connecting to the back of the head unit that wasn't seated properly and at an angle. Some brute force getting it in flat and now the AUX works great! :grin:
The higher wattage from the MP3 version of the head unit makes the stock speakers sound so much better that I'm no longer considering upgrading them.
EDIT: Apparently the MP3 version doesn't actually have higher wattage, yet still somehow the sound quality is better. Maybe it's placebo :wink:
