Hi all, I am hoping somebody may be able to help me with a problem with my radio (siemens ncdc2013). I removed the radio for a few weeks and when i replaced it the only function i can get is one radio station and nothing else. Non of the buttons work except the on/off button and the radio does not display to the screen. The screen still works and shows the start up and check brake displays but nothing to do with the radio functions. Is this normal after the radio has been out for some time and now needs 'resetting' at a dealers or may i have disturbed something else when it was removed. Any thoughts would be appreciated as it is very annoying listening to the same radio station all the time!!

I have a school of thought, but do not know the answer, but this may prompt somebody to give some guidance.

To the best of my knowledge, that radio is coded to the car with Tech2 and in order to be removed, it must be correctly deprogrammed - that is well documented on this forum.

My question though, is that if any married radio is simply removed from the car without divorcing via tech2 and then reintroduced at a later date to the original car, will the Radio and ECU still be in the same state to recognise each other? Theoretically they should, but uncertain whether they will in practice?

Not something I have ever tried, and wonder if some of the Tech2 guys out there can offer any further thoughts?

Yes, they should (and from experience do) work without any intervention.

Should still work, as long as the connected devices haven't been paired elsewhere.  There is a Tech2 setting to tell the radio what devices are present (cd, display, phone, computer etc)

Hi, Many thanks for your help so far on this frustrating problem.  Since my post things have developed further slightly. I had always wanted to exchange the display for a colour one and managed to find one in Germany with a 2013 (although i did not need it at the time!). These arrived today and as my current set up was not working  installed both of them immediately. To my surprise the new radio functioned in exactly the same way as my old one. The units have been depaired and the display does flash safe as i think should be the case. Is it possible that my old radio has somehow  gone into depaired mode when separated from the car , are the symptoms it exhibits consistant with a depaired radio? To complete the picture the battery has also been disconnected whilst the radio was out as has several other internal plugs although all is back together now with everything else working ok. Any more thoughts would be much appreciated.

If its depaired itself from screen (unlikely), its likely that the display is toast.

If you want me to attempt to pair/depair the new or old setup, see http://theboy.omegaowners.com and I'm in Brackley on the Oxon/Bucks/Northants border, about 6m from M40 Jnc 10

To complete this topic, after a visit to 'the boy' the cause of this frustrating problem was a defective Traffic Master box and or its wiring loom. Removal of the TM system instantly solved the problem. Thanks for your replies and to TB for finally solving the puzzle, i can now enjoy my omega again without having to endure radio Oxford all the time!!

Ps. if TB still wants the TM box for a post-mortem let me know and i will send it on to you.

Glad we got there in the end - and now you have colour screen goodness as well, lucky bugger

Did you check connections to courtesy light?

[jon]

Yes i did check the light connection but this was not the problem, it appears that when i disconnected the red wire to enable the release of the boot with the key in the ignition this also effects the operation of the light. As you rightly assumed the control unit was not sensing that the keys were in the ignition, because i had cut the wire that told it so! I had not used the car in the dark until i visited you and therefore had never noticed.

I am not the first person to notice this  (http://www.omegaowners.com/forum/YaBB.pl?num=1205347406) but have found a way around it that suits me.
