Dear All,

Does anyone faced this kind of issue or not?

I have newly installed 3M Crystalline at my windscreen, they also install together with a 7" of sunvisor. Please refer photo below.

Sales person have informed me earlier that Smart Tag will not function with 3M Crystalline, so I request them cut out a "space" to put Smart Tag on that location (that red dash line area), so I no need open my car window at the toll booth.

But still the Smart Tag not function while I at the toll booth, when put my Smart Tag on the highlighted area. The toll screen prompt "Smart Tag Not Detected" or "No Smart Tag" or no respond. I have tried to replace the 9v battery & borrow another unit of Smart Tag. But still cannot work..

Wish to seek advise from you all. Do I need to ask them to cut out the 7" sunvisor on that highlight area? Just leave the original dark shade without the 7" sunvisor. Do you think the Smart Tag will function as normal?

Please advise. Many Thanks..

I prefer hide my Smart Tag, and not put on the dashboard all the time.

Plus the Smart Tag cannot function behind the 3M Crystalline tinted. So only use that highlighted area for the Smart Tag purpose..

Do u know why he ask the question? It's not because of the Smart Tag device, but he tint itself.
He is asking for the solution.

Btw TS, the part u highlighted, still have the 3M?

TS, just hold your Smart TAG really close to the windscreen, like just before your Smart TAG will touch the windscreen... It should work... My car also all way CR series... Its either you open window, or you just do as above. It worked for me everytime...

erm if the 7inch u stick underneath the 3m crystalline mean the UV/IR still be filter by 3m tint,so the smart tag sure wont be detected bro..or i miss read bout ur info u cut ur 3m tinted?

No sir, the 3M have cut off follow the shape of that highlighted area, during the installation. According from the 3M installer..

Now that highlighted area left the original black dot + 7" Sunvisor..

Hmm...try to stick the Smart Tag there, open ur window a bit.
Else, poke a few tiny holes at ur tint using really tiny pin or needle

Just try like I said... It worked on all my cars with 3M CR series... Just hold closer, and no need to be specifically at the sunshade area.

well , worse case would be to cut a small square hole for the smart tag sensor ...

Ok. Thanks Bro.. I try again on this..

Added on September 30, 2011, 10:42 amThanks.. The 3M sales person also ask me to do this..

But will not be perfect on my windscreen..

I'm using 3M CR70 on the windscreen. Not even once I need to wind down the window when using smart tag. Just hold it anywhere above the meter cluster/on the dashboard area.

That's great. I'll try to do the same as you. Thanks..

I'm using CR70 as well, and yes i have to open my window to use the smart tag, but it's just a minor inconvenience as it really does help in keeping my car cool when parked under the hot sun.

But i've had it worked a few times while in car though (50% chance), but need to get very close to the bar before it gets detected.

ford fiesta? and you got your tint done at tintworks? the circled area doesn't work because the dots are too close to each other, unlike vios.

i have 3M CR70 on my windscreen too, no problem for smartag to work, just have to drive REAL SLOW (almost complete stop). the transaction will be delayed, it will show "no smartag" at first but continue to hold it until the transaction goes through.

better still, if your smartag has a lcd screen, u will be able to see whether smartag is transmitting as there is a indicator to show it is transmitting.

never have to wind down my window so far.

friend's vios have CR60 all over as well, transaction still go through with slow drive.

Haha.. maybe different tol has different sensitivity?

i am using genuine 3M crystalline solar film (CR70 + CR40) at authorized 3M dealer (with online certificate of 10 yrs warranty).



I totally have no problem using smart tag with the tint, just need to place the smart tag on my dashboard and it will work.

frankly speaking, i noticed there are a lot of ppl claimed that their "3M" tint got prob with smart tag, but i myself do not experience any. I do not know where you guys installed ur "3M" maybe just any outside workshop. but seriously i will nvr trust outside workshop that claimed to have 3M tint. in fact if you check on 3M malaysia website, there are only limited authorized dealer which sell it or so called qualified installer of the tint. The price you guys mentioned about the "3M" you have also varied. And apparently i believe most of you are told that there is only 5 yrs of warranty. and a lot of you guys do not even have the valid certificate on the warranty? maybe that's only what are being told by the workshop you did the installation?

especially for those who have prob with smart tag or even GPS, i seriously doubt that ur "3M" tint is genuine, as specified clearly on 3M website, their tint do not come with metal inside at all unlike vkool, it should not affect the smart tag as well.

i think instead of scratching ur head on this issue, maybe u want to confirm if urs is genuine in the first place?

for warranty, you should be given a code after installation to do the online registration.

im using cystaline 70. i do have a hole to use on smart tag but im not using the hole at all. juz put your smart tag device stick to your windscreen. and slow down ur car pretty slow. then will do.

i mean really drive slow and put your smart tag stick to your mirror. im using it everytime without problem.

Yes, I'm driving Ford Fiesta Sedan..

I done my tint at Pana S @ Cheras, 3M Authorised Car Centres which also listed they info too..

I'm using CR60 for my windscreen, CR50 for other screen. But this should not be the issue..

I do try to monitor the lcd screen on the Smart Tag, but it show nothing and the Toll booth also not responding. Until I wind down the window, and point out the Smart Tag. Then it can read on the spot..

I'll try to put the Smart Tag on the dashboard, and try again as you've advise.

Many Thanks..

Added on October 2, 2011, 3:24 amThanks Bro. My 3M Crystalline also installed from authorized 3M dealer. It is also stated at 3M website as well..

They do provide me the "eWarranty" site for verify our product.

The GPS is working fine, very fast detect location. Better than my last tinted film (VCool) on my old car..

As you've recommend and many member recommend too, I'll try to put on the dashboard to try again..

Many Thanks for your info & advise..

i agree. had the same problem before. damn... must drive slow slow. below 20km/h.

Just slow down below 20km/h will do. Need not really to stick to windscreen, I just hold it facing windscreen.

I have 3m as well.
I place it on the dashport using Velcro so that I can remove from sight when not in use.
For most tolls I have no problems if I drive slowly. It will read not detected first but as I move along it will detect and off I go.
For a few tolls it will work straightaway.
I think the key is to drive real slow.

i use CR70, drive slow is the only solution. Beware battery low

I use CR60 on windscreen. Initially I have same problem. But once i tried many method and i found out the most effective way to pass through.

1. The smart Tag must attached at the centre of the windscreen and just right above the dashboard and away from your seating position.

2. You have to drive really slow ~10+km/h to let the smart tag work. It works on every smart tag toll i went through with this method.

***The key point ---> Attached on right location + Don't rush.

All my cars are on Crystalline

I'm the idiot you see sticking his hand out of the window at the Smart Tag lane I refused to have the dark band at the top. If i go really slow through the lane I wouldn't need to wind down the window. I use 2nd and 3rd gen tags this one

Seriously though, the darker band also serves to let the smartag signal pass, but if it is stuck on the Crystalline (I highly doubt so), then it wouldn't work

If your car has a sunroof, you don't need to put your hand out of the window.

I also don't like the dark band on the front screen. I squeeze my smart tag in the area where it is not tinted... The top centre part near where my rear view mirror comes out.

Yeah depends on the car. If sunroof tinted then its the same, still have to wind back.

Just for the benefit of those who might be running into similiar issues with smart tag, I can confirm that using the new smart tag (slim full black which appears to have a bit better reception) I have had no problems passing through.

You do have however have to slow down a little bit more, and most importantly go closer towards the toll gate before it opens up.

Does it work with GPS?

Can detect smart tag if you jalan very slow e.g. basically just let your car roll over... dun ever step accelerator

I also have same issue..sighh

Same issue here, is it true the slim smart tag has better signal range? The fat smart tag can't be detected via the sun visor.

I thought many say the fat one is the better one?

My fat smart tag can't be detected through sun visor. Tested multiple times, battery checked, credit checked... The only thing unchecked is using the slim type. So I need verification b4 I went on to buy 1.

I believed one of the reason fat smart tag is claimed to be better is bcos after so many years the reader still functional, unlike the slim one which reader tend to be unreadable after certain period. But in my case I just want it to be detected behind the sun visor lol.

guys, smartag is based on infra-red, which is blocked by the tint along with the IRR heat rejection.

regardless of the fat/slim type, it will not work.
the only way is to cut a hole for the beam to pass through
else wait for rfid.

last time vcool also like that. if the car infront of me got 3m and vcool sticker, dont follow too close. likely get sangkut

I think you are spot on.

My case is exactly like the topic starter. I'm using my smart tag through a cut out hole of 3M tint (therefore no issue with the tint), it was fine until i install another layer of sun visor over the hole. My smart tag can't seem to be detected at the same location.

if adventurous, can consider taking out the smartag IR emitter and receiver, then place just the emitter/receiver on the windscreen. the rest can hide in glovebox

Could it using a metallic based material on the tint? Hence kacau the smart tag to work. Wheres there are some tint as ceramic based material so not kacau this infrared thingy

according to the datasheet its not metalised.
but its just pure blocking of infra red
