Title: Problem with  CCRT 700 Telephone
Post by: darren5354 on 23 April 2007, 22:33:46
Hi all, This is my first post & I hope someone can help? I have recently purchased a Vauxhall Omega Elite My secound one so far. It is equipped with a CCRT 700 audio system. This system has a Telephone facility. When I insert my SIM card, I can access my phone book & other facilities but for some reason I always get the NO NETWORK message on my display & I am unable to make calls. Could you please tell me the possible reasons for this? I have driven to numerous areas but still the problem persists. The only icon lit in the bottom right of the display is the signal strength icon. Do I have to have a certain type of aerial fitted? do I have to subscribe to some sort of service? Any help would be much appreciated. Thank you kindly, Darren5354.

Are you using a Voda or O2 SIM? Orange and T-Mobile won't work as they are not GSM 900...

The signal strength on the display, is it showing a signal? If not, does the car have an aerial on the roof?

Presumably you have the shortish stubby arieal still attached at the back of the roof....if a saloon....or longer dual arieal if an estate?

If yours is a saloon, the radio aerial is integral to the heated rear window, and the stubby is the cellular antenna.

If you have an estate, I believe the radio and phone are combined...

On a saloon the phone uses a small arieal on the rear of the roof....the radio uses an arieal combined into the rear window heater.....estates use a combined slightly larger arieal

Would there be a connection which was accessable that I could check????

If its showing a signal on the display, then presumably it has a signal...  ...presumably the SIM isn't blocked/locked, and has credit?

Good point & you have to register it 1st before you can use it...

When it happened to me a few years ago I unscrewed the roof aerial, removed the head unit and used a long piece of wire and a meter to check that I had continuity throughout the aerial. Discovering that I had, I decided that the unit itself must have developed a fault and then discovered that, at the time, Vx offered a reconditioned unit for £75 exchange. When I slotted the new one in everything worked again. This is probably not what you wanted to hear but I think that it is worth checking the continuity of the aerial before you do anything else.

Sorry - in reply to uk- to remove the head unit you remove the small allen screws from the front that stop you getting the standard u shaped removers into the holes then remove it in the same way as any car radio. The aerial connector at the back is fixed so it connects as you push the unit back in.
