  NAVI 950 DAB+ Upgrade
Posted by: - 5 hours ago - Forum: ICE - Replies (5)

I bet this has been posted before as it must be a common ask but I'm after a guide to upgrading an existing NAVI950 to add DAB+ capability.
Can someone advise the parts required (other than a U4D module and DAB antenna) and if any coding is needed for the system to recognize the new module?

Thanks in advance

Information Possible to install boot fuse board?
Posted by: Find_By_SQL - 2:nd-Jul-2020, 17:45:52 - Forum: Astra-J/GTC - Replies (3)


I know this is probably a stupid idea and question but is it possible to install a rear boot fuse board?

If it is possible I want to install TPMS and an anti dazzling mirror, unless all this can be done without a rear fuse board?

I look forward to seeing the comments, 
Thank you,

  Racechip S Tuning Box
Posted by: Marc_81 - 1:st-Jul-2020, 23:11:13 - Forum: Astra-J/GTC - Replies (2)

Hi All,

Tonight I spotted a Racechip S tuning box going quite cheap near me so thought I'd give it a go. I've always fancied a remap but just can't justify the cost at the minute.. £60 for the Racechip I can handle and get away with telling the wife!

Anyway I pick it up tomorrow and will probably fit it at the weekend. My question is has anyone much experience with the settings? Its for a 2.0 CDTI 165. I don't want to go in at the low setting and barely feel a difference but on the other had  I don't want to go in too high and risk problems. This is my first experience with a tuning box so any help or advice is much appreciated.

  2017 GTC Limited edition - Front wheel noise
Posted by: Nathan191210 - 1:st-Jul-2020, 22:49:30 - Forum: Astra-J/GTC - Replies (2)


The cars 3 years old now and has started making a strange sound from the front wheel when turning to the right. Its like a grinding noise. It started about a month after the front brake disc & pads where changed. 
It is most noticeable at low speed and happens when going forward or in reverse. 

When I first got the car i took it back to the dealer as at speeds of around 40MPH and above there was a wining sound, only noticable when the windows are open. They couldn't find a problem and I didnt push it at the time. Every year as summer start I get reminded of the issue when I open my windows.

I was thinking it might be the bearing but unsure, any ideas?
It would be great to get the part code of the front wheel bearings/hub as on Euro car parts it says there two fitments for my car.

My name is Callum, I have recently purchased a 2014 Astra J 1.6CDTI Ecoflex Tech Line because my old Volvo V40 D2 1.6 headgasket decided to blow :(

I've got a few things I'd like doing to it, a little work in progress but due to being an Arable farmer and contractor, not really got much time at the moment due to harvest coming up etc. 

My first plans for the car is to install ambient light around the gear stick and door panels, I then want to retrofit a Bluetooth module to my Navi650 since it hasn't got bluetooth streaming unfortunately :(

Here is some pictures of the new wagon Smile

Does anyone know of a rear diffuser that will fit an Astra Gtc Biturbo? I have seen quite a few on Ebay but when I message the trader they say it will not fit. Couch

  Using existing dab aerial on android unit ,
Posted by: pawex - 29:th-Jun-2020, 15:22:31 - Forum: Electrical - Replies (13)

Hi guys I got 2015 Astra GTC 2.0 ,
I have upgraded my radio to android head unit , originally I had cd400 plus with dab and usb ,
I know would like to use my existing shark fin antenna to plug in the dab in to my headunit ,when I took my old cd400 unit I didn't find any Dab connector there or anything there was is standard FM antenna ? I have searched the forums and found that there should be a seperate box for the dab and usb unit ,could any one confirm they actually exist and where about are they located ?

Photo Broken crankshaft bearing
Posted by: Fadii13 - 29:th-Jun-2020, 14:20:27 - Forum: Astra-J/GTC - Replies (1)

Hi guys, hope you're all going good
I had a problem with my Astra's crankshaft so I would like to share with you my experience so maybe I may have some advice from you or even answer your questions if you have any.

Actually, a crankshaft bearing broke while driving on the highway which caused the engine to stop, after several attempts, the engine never started because it was blocked.

the breakage of the bearing caused damage to the crankshaft so I decided to change the crankshaft for a new one.

Here are some photos of the engine disassembled and it is not yet assembled because I am waiting for the crankshaft which comes from Spain.

Here are some photos.

As you can see here, the pistons are in a good shape so I won't change them

And now those are the crankshaft bearings, some of them are in bad shape and one of them is broken as you can see it's on my hand, we found it like that in the oil :O
It's a 2.0 cdti 160 engine with an automatic gearbox with about 170 000km which is 105 000 in miles
Feel free to to replay if you have and questions or advice.

The engine is not yet assembled because I have not yet received the crankshaft that I ordered from Spain.
I will keep posting pics if I find something interesting to post. And sorry for my bad English, I'm from France.
