Hey guys! Trying to update from navi 600 to navi 900 managed to install the stuff from the memory stick but I can't do the stuff from the disc. I burned the disc with windows 7 manual burning. That is the disc
And the file which I need to upload on the disc is that one, right?[Image: https://uploads.tapatalk-cdn.com/2017061...41bea3.jpg][Image: https://uploads.tapatalk-cdn.com/2017061...3e8015.jpg]

Hi 
i want to upgrade m Navi900 unit to some after market unit, i want to keep it as stock as possible so steering wheel controls and centre buttons working and the climate controls on the screen.  i've read that the wiring is different for navi900 modules. 
I'm quite confident if i need to make changes to wiring ect but want to make sure its easy to revert back to stock. 
thanks

Hi guys

Has anyone upgraded their stereos to an aftermarket option? If so what to? I’ve seen the android ones but is there a certain model and how difficult are they to fit??

Hi! I'm looking for new android car stereo and want to install Seicane car stereo in my 2013 vauxhall astra. How to install it? Is it difficult to install this by myself or to ask the professional to help?

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 [size=small][font=Monaco, Consolas, Courier, monospace]13409130 "[size=small][font=Monaco, Consolas, Courier, monospace]HORN,ASSY.,400/500HZ"[

Hi everyone in this amazing forum, i would like to open this thread about how to change from my actual speedometer to a more recent one with bigger display and better inside light.
A step by step with pictures would help me and everyone who's interested in this!
My car is a Astra 1.4 petrol and i already have the better speedometer for the same model as mine!
So anyone that could help adding information to solve and enlighten us all would be amazing!!

Hi Everyone

As ive only got the GTC on a sport, its a bit basic on some of the toys.

What I was wondering if the wiring is hidden up in the headlining for me to upgrade the very standard mirror to one of the dipping models / auto wipers?

And if anyone is selling one with the housing, then please let me know before I go to ebay. If wiring is not present, what do I need to get it sorted, I will also need to get it switched on for the wiper function no doubt, can that be done with out havi

I have the standard factory fitted CD400 Plus and I'm sure this has more than likely been covered before but imIa new member so please bare with me. Is there there anyway to fit a Navi unit to a 2014 GTC or do I have to stick to the CD400? I would like to have Bluetooth etc with the added bonus of an upgraded unit
