I have a few random questions. Can you watch a dvd while moving? when using the paddle shifters do you need to let off the gas while shifting? is it hard on the tranny? will installing new tail lights or a short ram void the factory warranty?any other small tips/tricks that you have figured out along the way would be awesome, whether its for working the nav or whatever.

 

No ... only if you bypass the security override
No
Tail lights NO
Short ram ... depends most likely yes
Just explore the forum some and you will find some cool tips and trick

 

Exterior mods like tail lights, etc will not void warranty. Mods like SRI, exhaust, etc will only void warranty if the dealer can prove that the mod was the cause of the issue (Magnuson-Moss Warranty Act).
You don't need to let off the gas when paddle shifting.

 

nothing "voids" a warranty, not even turbo. There are many informative threads here about this.
