RW C55

I fixed mine by adjusting auto-zoom. I forgot how far I set it for maximum, but adjusting it to a smaller range will do it.

I just did a quick google, found these:

Manual for CA-R-PI.131

and this:

• Assign the buttons on the steering wheel to any of the 9 specific Pioneer functions. Volume Up, Volume Down, Mute, Track Up, Track Down, Source, Preset Up, Preset Down and Band.

I guess the PAC does more than 131.

I'm not having any of the issues others are reporting - mine works perfectly.

 

I was looking into the CAR-PI 131 but opted for the PAC unit. The Car-pi is cool because it displays PIONEER on your dash - but that is about it. On the PAC Audio unit you have more control to program more buttons. I use my phone pickup button for mute - something you cannot do with the car-pi.

 

I have the following controls:

track up/down (right hand top controls)

mute (right hand bottom left control)

Volume up/down (left hand top controls)

 

Thanks,

Well my CA-R-PI.133 does these: (<1s = press for less than 1 second, >1s = hold it for over 1 second))

"Up" <1s = radio Freq +or CD: Track +

"UP" >1s = radio presets + or CDC: disck + (not avaiable with F-series since no CDC)

"Down" <1s = radio Freq - or CD: Track -

"Down" >1s = radio presets - or CDC: disck - (not avaiable with F-series since no CDC)

"+" Volume +

"-" Volume -

"+"& "up" <1s Source (this switches between the sources available, i.e. FM/AM/CD/IPod)

"+"& "up" >1s Off/On (Hmm I havnt try this yet, I'm not sure if this works on F-series or not since we can't turn the unit complete off)

Again, I dont know about 131 since I have a +05 C-class...

I'd say just go for whichever is cheaper. Sounds like they do the same thing.

I'm using CA-R-PI.133 made for 05+ C classes, and the link above is for pre-05 C-classes. All buttons work except that the phone answering & hanging buttons.

Why mod it? Its the exact same reason why we put these units into our cars. . Why go thru all the troubles putting these in-dash nav. in, when we can just buy a map? We want things to be easier.

In AV Settings, I think, there's a Mute option. You can select between having it mute music, attenuate music, or leave music as is and talk over it.

 

Note: you can change the setting only if you set audio source to OFF.

 

Thank you for your response. However, I want the voice to be off. I don't want it to mute the music, or leave it as it is and talk over it, I just want the voice to shut up, basically

 

However, when doing this, I am experiencing the music 'hickup'.

Well you can leave the music as is and then mute the guidance voice

What did you come up with ?

I ran a new 12V constant from the fuse box and it worked.

sounds like the factory wiring that is powering the head unit doesnt have enough juice for the radio. you need to run a new constant 12+ wire and run your own chassis ground to prevent this from happening.

Fixed the problem today.

THANK YOU!!!

One more question, looking at the diagram, I believe that I connected my front speakers from the F90BT to 3 and 4 together (since one one set of wires connect them both) and the rears to 5, does that make it 4 ohms for each set?

Again, sorry I'm noob in these stuff, so please dont flame me if its a stupid question.

Hmmm, I just did some research and unfortunately, I think my speakers are 2 ohms.. what should i do now

Thanks for the suggestion- I'll try that this weekend when I have time.. meanwhile i'll keep the volume down

Do your headlights dim when the bass hits?

Hey, thanks for the reply.

I didn't pay attention on the headlight, I'll go check it later.

My first guess would be the draw from the amp is causing a large enough voltage drop that the head unit reboots... How big is your sub amp?

I dont think I have a sub amp, all I did was bypassing the stock amp and run the speaker wires straight from the new HU- some members on a MB forum suggested me to install my HU this way so I dont have to worry about the fiber optic system on my car... Would this be a possible cause?

I don't know if Mercedes need the "big 3" upgrades, but that would be my first suggestion, if this is the problem... A capacitor could help as well, but upgrading the electrical system overall is the better solution...

Can you explain more on this upgradge? Sorry I'm a total noob in this field.

Hi, I did search but didn't find any result similar to my issue.

I have an F90bt, and it keeps rebooting when the bass is high enough.

When I use "Powerful" in EQ setting, Loudness to "Mid", and when the volume goes pass 15, my HU would reboot if the bass of the music is high enough.

If i pick "flat" in EQ setting and change loudness to "off", the unit would reboot when the volume goes pass around 25 when the bass kicks in.

What could be wrong?

I have a '05 Mercedes-Benz C-class with stock H/K speakers.

another thought.. would it be possible to have the brake lights on when you actually steps on the brake? Would be a cool feature to have

Well this is mine

ASUS P750 (Windows Mobile 6) and F90BT with 2.0 firmware

So far everything is working flawlessly.
