Nah it was fine, due to a warranty can bus replacement just before I owned it, I didn't need to
Change it thank god
I kept leaving the unit on radio when I switched the car off and
You won't get a splash screen from leaving it on radio as that can come on instantly and doesnt
Require the use of the HDD.
Plus if you unlock the car and open the passenger door on a quiet road,lean over open the drivers door from inside you will
Hear the unit begin to boot up if it's working properly
I should of updated this post really
