Title: CCRT700 Mobile Phone puzzles...
Post by: PaulW on 14 September 2007, 09:52:28
I'm trying to get a SIM card to work in the CCRT700.  It's a new O2 PAYG SIM, I've put £10 on it, and its all activated according to O2.

The SIM has 24DTXTAN - Prepay Text Anytime 2G (4DM) on the back, so it's definately a GSM SIM and not 3G (also confirmed with O2)  They also said its a dual-band SIM, so will work in single band phones (GSM900 or GSM1800 only).

When the SIM is inserted into the radio, it just sits there saying searching... and then goes back to the radio/cd (whichever was playing)

I've also gone through the Menu system of the phone as follows>>

Menu -> Network -> Pref. List -> View List

No O2 or BT CELLNET UK Listed, just a bunch of foreign German/French channels

I then go to>>

Menu -> Network -> Pref. List -> Add Network -> Nets on Air

The radio then displays 'Network request', and after a few seconds, says 'No Network Available'

If I go into Known Nets, it lists 'UK CELLNET' so when I add it, it is then saved under the Preffered Lists, but still won't access the network.

I have an actual O2 phone (other SIM, dif. number) and I get signal with that where I'm parked (driveway) and same with my Orange contract phone, but the car phone just doesn't want to play ball.

Are there any fuses which relate to the phone aerial?  Also the aerial on the car isn't a regular 'stubby' but a tall aerial, like the standard radio one on the Corsa 'B'.  Would this make a difference at all??

Cheers

Paul

Sounds like your aerial might not have a built in phone aerial.

hmmm strange  :-?

I thought the rear screen acted as the aerial, and the roof one (if fitted) was for GPS/Phone...

I'll get a picture up of the roof aerial, but I'm buggered if I'm gona take the rooflining down to check the wiring underneath  :-/

On the back of the radio are TWO co-ax connectors .. one for the radio, one for the phone, on mine the phone one had been disconnected, checking continuity between the short stubby aerial and the actual unit showed a cable break, eventually found about 3 cm from the radio, under a clip that secured the cable to the DIN tray, repaired this and the phone works .. although the signal strength is lower than my normal mobile ..  I'm guessing thats 7 years difference in technology !!

I had the same problem and when i checked my aerial connections at the aerial end i found some one had disconnected the aerial cable going to the head unit and connected another fly lead to it for another after market phone.  

Before i changed the cable over i had bugger all signal unless i was beside an aerial mast. Now i get full signal more or less all the time.

You just need to take the back trim off that covers the rear windscreen brake light and you can drop the roof lining just enough to see the connections.
