hi does anyone know what the pin is to the 2 aerial amplifiers as am trying to fit a cd500 but think am not powering the amps thanks

In this How-to, you'll see how you can replace your dinky single horn with a Dual horn.
Without removing the front bumper.


It seems Vauxhall decided that it was a good idea to put single horns in on a randomly select few Astra J's, no one knows why!
Cause it sounds like a clown horn on big cars like these!
So lets fix this!

Part number for the horn:
GM 13409130 "HORN,ASSY.,400/500HZ"
(or look up Astra J horn on Ebay)


Step 1:
Jack up your car, lift it or drive on ramps. (Be careful with ramps as the front end is rather low.)




Step 2: 
remove the left side (UK passenger) side fog light surround.
by Following this lovely How-to!
https://www.vxoc.org.uk/forum/Thread-How...d-Facelift


if you look in the newly made hole, you'll find the bracket that holds the horn in place!




step 3: 
Removing that clown horn!

Reach in from underneath and disconnect the horn's electrical connection.
you can then undo the single bolt holding the horn in place.

Once that bolt is out, the horn can be pulled out from underneath the bumper.



Step 4:
putting in the better horn!

Slide the dual horn from underneath the bumper. You can then hold it in place and bolt it in place form the fog light hole!
Once it's all bolted in, connect the electrical connection. test it out!



step 5:
put the foglight surround back in by reversing the tutorial mentioned in step 2



That's it! 

Now your fat Astra won't sound like a Corsa B, but like a Insignia instead!

Result:

Single horn:


Dual horn:

Howdy folks!

First of all i would like to apologize before hand about my poor English, it's not my native language!

I was amazed by the extensiveness and well organised this forum is compared to most vauxhall forums!
So i immediately wanted to join this community!

I've owned all generation Astra's except for the MK7. 
Every single time i picked the 1.7 ISUZU block as it's my favorite little Diesel engine ever since it came into production!

My first car, the mk3 (1994 Saloon GLS 1.7TDS):

Lovely little workhorse had her for many years, but rusted like hell and the turbo was on it's way out!

The MK4 (2001 Comfort 1.7DTi):

Had quite some fun giving this car a OPC look! but had leaking injector seals, and overall it didn't drive very fun as the rear end kinda sways everywhere... That and i backed up into a pole, which ruined the rear end pretty badly!

The mk5 (2007 Estate 1.7CDTi) 


Didn't enjoy this car very much, it felt very cheap.. the paint was very poor and everything rattled. This was probably their worst model in my opinion, crashed it after owning it for 3 month! Don't miss it one bit!

And the current Mk6 (2013 cosmo 1.7CDTi 96kw start/stop):

Quite a lovely design, and i love how they upgraded the quality significantly compared to the mk5.
I avoided the pre facelift models as they still have the older generation m32 gearboxes. 
That and the front end of the facelift looks quite allot prettier in my opinion!

Quite love the AFL bi xenon headlights on there! That little dance they do is awesome. But i must say the adaptive high beam is rubbish, it reacts way too late and i end up blinding people easily. So i leave it off!

The heated leather seats do sadly suffer from the well known faulty wiring, but i don't bother as i've never found myself using heated seats ever.

THe navi 900, whilst okay for general use..I was quite amazed that a 2013 car does not have bluetooth audio streaming. A huge letdown! But i use a thumbdrive for now.

I did have one major issue with this car, i had a severe waterleak comming from the left side roof rail. It soaked the spare tire well and fried the towbar module.
Dealer thankfully repaired it all under warranty as it still has warranty till november


Now onto the modifications i've done so far!

-Added the little shelf, apparently they don't fit these to facelift models anymore.
Dealer quoted me 125€ (100 ish quid), so i went on ebay and bought one for 10€ 



-Replaced the horn with a dual horn!
That awful dinky little horn, how on earth did they decide this was okay on a full option cosmo... Went on ebay, bought the GM dual horn for 20 quid and replaced it!

Quite easy to do! Pull out the left fog light and you'll have easy acces, no need to remove the bumper.

So a Few weeks ago i bought my first GTC its a 16 plate and so far I'm happy as the proverbial pig, great car fun to drive. A little under powered at the moment but a remap should sort that so just thought I would introduce my self and say hi all.

Hi everyone can someone on here give me the wiring diagram for changing my astra gtc 2013 cd400 to a cd500(navi 500)
want to upgrade my radio but need help thanks

After analyzing the various alternatives to replace the CD400 of my 1.7 CTDI 2011 for an android I opted for this model https://es.aliexpress.com/item/10-4-tesl...63c0xAeGkc
It arrived at 15 days in perfect packaging.
Aided by the how to of the forum the assembly was not complicated at all, although it takes 3-4 hours if you have prepared it well, but it can be double.
The truth is that I can not be more satisfied by aesthetics, performance and quality / price:
Android 6.0, 32Gb ROM, 2GB RAM, Sygic pre-installed, etc.
Summary evaluation:
Radio 7/10 with respect to CD400, no problem of power antenna, goes direct through its connector
GPS navigator 9/10
Sound 8/10
Functions CAN BUS 10/10 All perfect even control air conditioner.
Perfect steering wheel keys and no need for any adjustment.
I want to emphasize that I had many doubts about these functions and the CAN BUS but it works EVERYTHING to perfection and it is enough to plug in and that's it!

I added a rear camera and also works for CAN BUS.

Keys lock doors, warning, ESP are perfect and with its light.
The screen has the device at the top and it is very small, it fits without any problem in its hole and the adjustment to the original frame is perfect.
The only drawback is that it comes without any instruction paper at all although the Chinese seller does respond minimally to the questions.
I've related some aspects over the installation at the brother spanish forum:

Greetings!

I have manual rear windows and iv for the complete set up for electric can they be activated by using tech 2 device

Hi Guys,

Literally the proud new owner of a 2013 Astra 2.0CDTI Ecoflex Elite, moving on from a Seat Leon so getting used to the changes!

I'm not what you would call a car modder, however having owned it for one day I've already decided that the head unit has got to go, will probably look in to getting one of the android head units installed instead.

Anyway, just wanted to say hello, was only joking about the leaching!  Most likely see you in the ICE sub forum! 

Cheers,

Steve
