Just as a point of interest, i went into Halfords to see about getting some new ICE in my golf. I had the gamma stereo, standard speakers and the 6CD autochanger in the boot. I also had an old amp and sub from a previous motor and wanted to install it into the golf.

My initial idea was to remove the gamma head unit, as i wasn't particularly impressed with the sound quality, and put in something nice and new and shiny! I wanted to keep the CD changer and plug my amp and sub into the new head unit.

Unfortunately the knob in Halfords told me that my CD changer would nt work with anything except the gamma unit, the gamma wouldn't accept a sub and amp, and CD was dead anyway so i was wasting my time. He then went on to try and sell me ?800's worth of amp/sub/speakers/mp3 player. I told him i'd think about it.

Since then i found out about the PC3-11 adaptor which plugs straight into the back of the gamma stereo and converts the plug port into pre-outs for an amp. I promtly went back to halfords, paid ?12 for one and installed my amp and sub into the gamma unit.

Result: Kept my 6 CD changer, kept the head unit and thus got a nice stealth look, the sub and amp kicks out some serious bass, it actually sounds better from the gamma stereo than from any of the sony and alpine stereo's that i previousley had it plugged into in other cars.

I never rated the gamma stereo and standard speakers, but with the addition of a sub and amp through the PC3-11 adaptor, the system now rocks.

Anyone who is thinking of upgradeing the gamma unit, i would strongly suggest you try the ?12 adaptor before you upgrade door speakers and head unit, you may be suprised at how good it sounds!

Thats how mine is wired and have to say it sounds great.

No messing / risk with the K line etc and you retain the TIM feature on the gamma which aftermarket head units don't seem to have. The only thing that's bad is no MP? functionality with the gamma.

You will find that the system sounds even better with the addition of the Sony Sound On Top amp (check my sig for the exact model) to power the door speakers. Just gives that extra bit of volume/definition that you need from the gamma when you add the sub.

Gamma only outputs 17 Watts so runs out of puff fairly easily, so the extra bit the sony gives is very usefull. It is also small enough to fit in the glove box (the bit at the top where the books are supposed to go) and plugs straight into the factory loom!

Don't ask me where to get one thoug, I got mine thru the calssifieds on here! [;)]

just out of interest putoline, do you get any noise from your setup? like alternator whine or buzzing or anything?

If not, then what year is your car/headunit, or do you know if its a Blaupunkt or a Sony job?

The TIM facility stores traffic reports in some kind of RAM memory on the head unit. First thing I do when I jump in the car after work is hit the TIM button and listen to the traffic report that the Gamma has saved for me, I can then decide which way home. It's a great feature.

P.S. the best station in London for this is LBC 97.3, reports every 10 mins so they are never out of date so to speak.

Calum.... Noise, I personally don't get any, if you do, check and double check the earth to your amp and make sure your interconnect is decent quality.

As for MP3, my last headunit in my old car displayed the ID tags and showed what you were playing. I'd find it quite hard to manage my MP3's without this and would assume the gamma is unable to show this info even with the adaptor ?

Looking at the Denison units... They do a nice Hard-drive unit that that would go very nicely with the Golf's interior (colour & illumination).

But i'm really after a Hard-Drive MP3 player with a DAB tuner thats One DIN sized..... there doesn't seem to be one at the moment.... or is there ? ..... err for reasonable money that is ?

Reply to calum cousins:

The only noise i notice, is when i turn the ignition on there seems to be a vague 'power up' noise. I'm struggleing to describe it, but it's like the amp is getting an influx of volts and it creates a background hum just as you power up. Apart from that theres no interference or buzzing, and once the tunes kick in it sounds sweet as a nut. The unit itself, i never checked to see if it was the Blaupunkt or the Sony, but its strapped into my 2001 V6 4motion, if that helps.

Reply to TDI BOY:

I like the sound of this Sony XM423-SL Amp, when you say it plugs straight into the factory loom, where and how? Is it literally a self powered plug and ply unit, or is it a bit more complicated than that? Can you give me a bit more info about wiring the thing up?

Cheers.

TIM feature.....never realised I had this! sounds pretty good tho.! How does it work (i dont have a manual for the Gamma ya'see..!)

Noise wise, I know its defo not my amp earth, interconnects, etc, but definitly something from the headunit area or cd changer...I have tested the amp with an aftermarket hu and it was fine.

It makes the noise when the cd is playing, but not when the radio is on, which leads me to believe that it is a dodgy earth on the (facia mounted) changer. However....it draws its power from the gamma hu, so not sure if there is a way around it....

do you think it would be worth trying to earth the chassis of the changer?

We'd need a few more details as to how it's all connected to offer any advice,and please DO NOT use cameraphone photos,they're worse than useless for closeups.

Blimey.

5 year thread re-surfaced (well almost 4.5)

My advice now the early days of suffering it, is to junk the gamma (or keep it safe for when you sell the car) and get almost any aftermarket headunit. Even the cheapoes will be better.
