Will shifting up via paddle also reduce rpm and resultant noise as well?

hello everyone, i'm a first batch CFE owner and a very very silent reader of the preve tread since april 2012, had my OWV changed twice, side mirror once, and I still can't or don't know how to use the GPS system (i don't think it's working as it should). I regretted not doing the Sierra Glow when I first got the car, cos I don't have the money for that since all my savings went to the d/p for the car, i'm tempted to change my rims and trying to keep my faith in the preve that it is the best proton car yet...

there are a few things i'd like to ask, if anyone could help it would be great.

1) Is Section 13 SC still in operation? if so, I will need to call in advance before sending my car in for service, right? Can anyone share the contact number please? I've been sending my car to Setapak SC since day 1, and it's time to try other places.

2) There's something wrong with my reverse sensor alarm aka sound, everytime i reverse it's only doing "teeeeeeeeeet" like something is really really near, instead of doing "teet" "teet" "teeet" "teeeeeet" "teeeeeeeeeeeeet" as I'm reversing closer to the wall. Anyone got the same problem?

3) Is it just me, or the audio speakers suck? I had better speakers in my wira last time. I can't turn it up loud enough to play my music without the speakers sounding like the no-brand cikai cheap speakers. With that said, if I change / uprade all my speakers, will my warranty void?

I hope someone can help me with these.

Thanks

what? they supposed to paint or painting is extra? what colour is your car bro?
