It could be that their DSP filtering is not optimized, where the signal in the pass band got attenuated too much. If its a software issue, then its possible for Clarion to fix it in the future (if they are willing to do so). Otherwise someone will have to do some hacking. So far, I don't face this problem with my tuner yet...

wa, long time no free surf web, now already v8 and page 10....

just now my family go kuala selangor by new highway, suddenly 1 new altis 1.8 150 like pass my dad, then my dad like on fire , accelerate till 190, thn all the way cruise at 160 , quite straight that new highway road like wave a bit. but save around 30 min from rawang to kuala selangor.

bro XC, so how your HU going? problem solved after so many change?

They are willing, as XCInspire can be witness to.... its not the DSP issue, its mainly the tuner chip problem.... donno what setting they use... and i still think their noise reduction filter is too high, and this could have been set in the chip, thus the reason they tried diff tuner chips for XCInspire...

You will not have much of this volume issue if you drive in open spaces like arnd PG, you will encounter this in places with lots of high rise and in long highway drives, where there is plenty of signal loss due to deflection and blind spots...

Added on August 1, 2011, 12:02 amYes it does...

It dims on when you unlock, and brights when you open the door... and dims off when you drive start your car...

It also dims on when you remove your keys, brights when you open the door... and dims off when you lock the door...

i think this feature is normal, as my fren fiesta 1.4 radio also like this one will lower volume itself, but fiesta one worse, cause will lag some time, i also don know why, cause i hearing fm only not disc, but also will lag.

In that case probably is the filter design in the tuner is non-ideal. Can't really comment unless we see the frequency response of the filter.

The tuner chip, we must use the same one manufactured by Clarion or there are alternatives? Anyway we can use back the dual-tuner chips?

Ok chillex.

My colleague is an engineer in the engineering design department handling the electronics stuff in the car including the radio.

and yes the chip is the cause of this.

R u satisfied?

That i leave to you to find out... u seem way more qualified than me in this area.... me kaypoh king....

But if he is in that field, obviously he knows that single chip tuners does have noise reduction when it detects noise, and for him to say that volume reduction when there is static = BS, almost equates him to telling us that what we are hearing every day and time when we drive our car is all in our head and its not true...

At least your qualified friend have admitted its the chip as the root cause... to which we, and even Clarion, have admitted as much... we have never said this is a Clarion "feature" but have always maintained its is a Clarion HU problem...

So what your qualified friend say in the chip causes the volume reduction..?? Or is he maintaining that the volume reduction is BS..??

IMHO, its more like the filter they used is not the appropriate filter. I think they used a normal band-pass filter with a pretty big attenuation factor. Would have been better if they could use a weighting filter instead (where the pass-band gets amplified). I'm not very sure what is the constraint on their side, but i am pretty sure they would have taken this into consideration as weighting filter is a very important type of filter in audio regardless analog or digital.

Haha i'm not going to open up my clarion unit to experiment. If anyone want to donate to me, I will more than happy to dissect it and depending on the DSP chip and IF I could get their code...I might be able to do something. No way I'm going to reverse engineer it, its even harder to do that compared to reversing x86 codes....

Clarion probably intended this noise reduction to be a feature, but it did not function as properly as it should and in the end....it become a half-baked feature in the end.

There is this shop in Paramount, opposite Giant, beside a corner lot coffeeshop.

Proprietor is Mr. Sunny, I am very happy with their service thus far.

why on fire?? tak suka altis pass through inspira? cannot like that one... family come 1st.. bring u all at risk...
pity you...

haha, no la , my dad just try what this car capable of only, and my dad not some drive very slow uncle, few years ago , when we go thailand travel, 2.00am like that i saw he doing 195km/h on waja.

btw, here the thing i recently add to my inspira.

I dont know the details of that said chip actually

about the volume reducing thingy, maybe i used the wrong words lol. its not BS. I mean the radio should not have this issue in d first place so the volume wont reduce suddenly everytime there is noise

Picture pls...

Nice stuff dude!!!

Wah, you dad can join daredevil club di.. haha...

HU problem no solution yet. I revert back to the first/ori version as the other "fixed" units do not offer proper fixes (in the end the noise level is more unbearable than the fading volume) due to the board design and single chip tech. Proton and MMC (yes MMC cause they have to certify what is put into their CAN-BUS circuitary) "ok-ed" this design, so they cannot change the board design as it involves cost and unless more ppl complain to Clarion or Proton, they cannot justify the need pay to change the design. However I have pushed Clarion to try to proceed to 'jaga' their reputation... lets see if any updates but this will be months... What I do like is Clarion did listen and reacted to customer's complains.

On why they use this single chip design is due to cost and its more accurate, most brands have moved to this tech. Maybe Munky's fren can shed more info to this.

To those having this problem, pls go to Clarion Msia website, click on Contact, email to their customer service to file a complain for this issue. Only then they can get the statistics of how many really have this problem. You can complain to Proton too (to get them to write in their buku 555) but the complain usually does not get escalated.

@pip_x, thank you

@XCInspire, i get it at Brothers kelana jaya, rm78 ( stick it yourself price), if you ask him to stick need add labour charge.
indeed it small a bit but you stick it to most outside(like me) still can prevent scratch directly to our paint.
its a non led version, i dont like led version.

I have yet to face this problem, maybe one day I need to make a trip to KL to see if i face this HU problem.

Bad news for ppl's who's waiting for the Merdeka promo. I asked my SA's big boss, he told me that the promo is not as good as July's one. RM3500 discount + 2years free service + 3 years warranty.

Is this the corner coffeeshop opposite the post office ? They serve good claypot chicken rice...cooked over charcoal fire

Anyways, will check out the alignment place. Thanks.

You will only have issues when radio reception is not good. The Bukit Bendera very high, perhaps the radio towers boardcast very strong signals.. haha... In KL, too many tall buildings and electrical interference... I also have no fading issues when I travel on the highways... In one recent trip to Sekinchan, no issues encountered, happy until reached Bdr Sri D'sara... then fading came back
