Hi

I'm about to install a new head unit - Alpine CDA 9811R, which requires a connection directly to the battery. I've found a cable route and obtained a fuse holder / cable etc.

What happens when / if I disconnect the battery ? Is there any alarm / immobiliser issues etc

Any advice greatly appreciated

I found my alarm went mad on my MY03 Sti when i pulled the battery off... I think if you put the ignition on when disconnecting it stops the Alarm going mad!
( well it shut mine up but dont quote me on it! )

This is what I suspected.

Anyone else know what the correct procedure for disconnection / reconnection is ?

I suppose I could always check with the dealer !!

There should be a valet mode on the alarm which should avoid this, last time I did similar was on the old cossy and all I had to do was disconnect it with the alarm disarmed and then get ready with the remote when you re connect to shut the alarm up when it goes off,

disconnect the battery at will ... no problems at all ... i've done it loads of times to replace bulbs.
