I'll be installing an audio upgrade to my XLR and it suggests that the battery be disconnected prior to installation. Am I in for any surprises when I do this, such as loss of memory settings, needing to recalibrate the window close position, etc. or will the car remember these even after disconnecting and reconnecting the battery? Also will it lose the maintenance diagnostic information stored in the computer? Thanks in advance for any help.
