Has anyone installed running boards or mud guards on the LR2? If so, how difficult was it?

Also, Maybe I have not read my manual thoroughly, But when listening to the radio with car off forawhile,
do you have to restart the car to operate the windows or sunroof?

Thanks for any info

 

I did install mudguards and The rear-ones is very easy but the front one is a big PITA. Doesn't fit well and require some drilling, cutting and fitting. [:@]
Instruction is very strange and in my case there left and right mud-guards was marked wrong. I love diy projects so it's ok but if you not into it - go to the dealer.
BTW - it marked made in Switzerland!
