just so I can put it all into one thread without hijacking someone elses

thanks for your reply on my other thread pecky

this is what I have done

bought a uhp4 module and got code

divorced my head unit and display both said safe

fitted uhp4 module and activated security with the code I have for uhp module

Bluetooth works perfectly takes and receives calls but radio wont pair head unit in with the code (pecky may have answered this for me)

I have ordered a eeprom reader , I know I cant read the up4 module that's possibly a job for pecky, but could I reflash the eeprom in the head unit with the code changed to the up4 one.... as you can guess im clutching at straws a bit or could the radio code be put in with tech2 to marry it all up .

im fairly ok on electrics but this has stumped me as really its software related, what im really looking for is a diffinitive answer so I can get it all sorted as I know everything works
