their panel only limited to ecotint and 3m. 

by the way, chances of u claim warranty due to windows tint, is almost as good as nil.....unless u really bad luck

See whether you want to go lower than the JPJ COMPLIANCE VLT

Other potential error is some newbie tint, spray too much water, then, sip into the car electronics. 
Oh, that one not outside panel lah....that one SA side deal with the shop  will affect warranty also lah if they want to make issue out of u. Not sure about u, but, my experience, if I go do outside, inquire around, the price cannot lower than what SA offer one (for same brand lah). Reason because the shop oledi kaotim with the SA, not to undercut SA and pissed them off just for 1 customer, but, lost potential of future customer. Old car, maybe yes.

I plan to do 50, 35, or 50, 20

Actually, the price can nego one......as rule of thumb, u can nego up to 30-40% from the initial price they offer u one.....this is what I got.

The technique (hope OP don't banned me for derailed topic)

1. Use time as your advantage. Immediately after book car, ask SA what panel he got. Don't stick to just 1 brand, instead state your requirement, ask for proposal which brand or tint model fit your requirement, at least 2 brand. Never ever tell them your budget outright. Yeah, u can let them guess, but, never tell them specifically.
2. Some SA will be lazy, direct ask u talk to their "agent" at tint shop (bingo), some SA will do it on your behalf. Try to talk direct to tint shop, instead of SA. Tell SA u mau visit tint shop, to see their workmanship, their workshop condition coz quality of tint is same for same brand, but what differs is the workmanship. Purpose is to get to know PIC at tint shop, don't forget to give them your contact with them.   
3. When u at shop, further understand different type of model they have and the price. This can be done via website also. But, price, u need to take photo lah. That's why I said, never let them know your budget, just tell them your requirement, then, at shop, go +/- 1 or 2 level model within your requirement to see the price (usually this price is higher than SA offer u one, but, u already know how much discount u got).
4. Then, start negotiating, direct with the shop, cc your SA, as courtesy. Reason, coz u duwan SA to hold too much info. See which shop can give u better price and/ or better "upgrade" quality tint that u had in mind

Good luck and happy negotiating

What spec u buy? Cancel now n book from other branch... Haha

So just wait patiently for the queue. Do u know average how much car a branch will get for each model? There are 3-4 people in front of me. Hopefully can get by next month.

Haha, I've asked this question before, it seem like whenever you add latest folder in your USB drive, it will show at very bottom of the list.

I've tried few steps, rearrange the folder in windows sort by name, delete the hidden system information folder. All not working, it seem like the HU sort by last modified date.

u told her that I mod my car? I never told her before le

Anyone got problem sync the phone contact, music, etc into the audio system? I just manage to pair the phone via bluetooth, but, unable to sync the rest. Please help

Mine is iOS, so, not sure if applicable for you or not. In bluetooth folder in your phone, there is option for you to choose whether to transfer phone contact, phone history to HU.

So, just tick the transfer of phone contact (it defaulted as un-tick).

Have a try......
