First post, sorry if its the wrong place.
Plan on installing a new head unit in my Mk4 Astra GL.
Only recently started driving and the car is stock. Never tried modifying anything on a car before.
Confident with my ability to install a new head unit without any foreseeable difficulty however I am wondering what effect disconnecting the battery may have on the car electronics.
Common-sense tells me to disconnect before doing anything so not to accidental short anything out or give myself a nasty shock or bust my new head unit.
Can I expect to run in to any problems when I reconnect the battery?
Cheers for any help.
