Got to give my gaffer a good drink but still cant believe one come up so quick .many thanks for your help mate and ill cancelle my appointment,thanks again carl.
hi i am new here but i am thankful i found this forum cus i have exactly same issue. cd70 radio and cd works fine but sat nav shows blank screen n it wouldnt even take a cd.i am curious to know how u got urs sorted pls.cheers
well in most cases they can be repaired but cd70 cost isn't too high, so sometimes its better to go for replacement
from experience have spent nearly 3 days checking components was lucky found dead transistor sourced replacement but than problem started can order from digikey or rs components but only in huge quantities so pointless to repair as parts and delivery are nearly at same cost as unit thats if you do for itself if for someone than add job costs and you end up £££ as no one will buy few hundred item and use one
and another thing is i don't use cheap parts from china
but don't give up open it check for blown components, burns, etc anything what looks like strange post some pictures will try to help you
I also have the same symptom CD70 head unit! The navigation panel on the poor, in which the antenna connector is blue!
Unfortunately, I do not know what is wrong inside, but replacing the whole panel has solved the problem!
Do you know which transitor it was mine jus went tits up after I remove and installed
no idea, i just normally throw them out, but would be good if you can work it out
Soulman you change only the transistors and its ok?
No, I said I throw the board away and fit another board..
Ok.I Will test witch component is defect and keep update
