2005 Vauxhall Astra infotainment system drains battery

Sounds like a problem with one of the modules,a fault read may bring this up or may req, ring break test to pin point could be quite tricky to diagnose,You could search internet for common cause or ask dealer.

Hi

There were problems with early stereos causing battery drain, basically, the radios were turning themselves on!!

Firstly go into the settings and make sure ignition logic is on, if this was off, then try it overnight, if battery still goes flat, a new recon radio, which has to be reprogrammed, and you need the security pass, will have to be replaced,

Hope this helps,
