did you unplug the battery when you changed the unit? check all your fuses, maybe unplug the battery for a few min and try again.

the joys of modern vehicles :bang: had a google for ya but can't find anything, maybe email these guys http://www.caraudiocentre.co.uk/contact-us.htm

yep disconnected the battery re disconnected and left it over night thanx for your help

did you do a lot of testing of new head unit with out engine running? low battery power can cause loads of errors to pop up.

good luck with it man

:yeahthat:

Disconnect the battery and put it on charge for a few hours.

Likewise you left the canbus network disconnected I assume and didn't just plug it into the back of the new head unit did you?

What scanner are you using, the last two issues should be leaving fault codes.

Your Fuses have burnt out, Just check your user manual to see which ones they are. Hope it helps

hi the battery ok.
is the canbus the different colour block things they haven't been reconnected as the double din in now doesn't have the connections for it
we have a v gate scan no codes are showing up which i think is a bit strange

checked every fuse in the car all ok

my dad noticed there's a wire behind the head unit that moves a lot more then what it did before going behind the dash so he thinks somethings come unplugged somewhere hes gonna investigate it when the weathers better

not a loose wire :s
