My 2006 armada just just got a new pioneer in deck gps/dvd/mp3/radio etc. done today and also i bought a module to make the steering wheel audio buttons work for my new in deck pioneer but my rear audio volume and channel doesn't work and also my climate control doesn't work. I'm not sure either i need to buy another module or what??

You need to talk to the experts on auto sound issues like this one.
www.crutchfield.com

causes:
1) Check fuse box for blown fuse(s)
2) Steering-Wheel cable. (check for dust inside where the wheel rotates).

Wish you success

absolutely no idea ,do you have anything else plugged in that could cause the sound cut off although you say the radio works?or has a plug come loose in the back of the radio ,you could try one of them radio fitting centres as you never know some young lad comes out presses a button and it all works as you had the mute on or something but the radio works ,is it a built in cd player or a remote unit ? in my time a 8 track was the in thing these modern things are welll beyond your ancient dinasaur here .

Complain to the guy who put it in, who will complain to the manufacturer.

My $80 BLU smartphone has a better GPS. Just sayin'.

HONDA INTERNAVI CAR NAVIGATION SYSTEM
I am in srilankan. I have bought a 2010 Honda Cr z imported from Japan. The car has an imporessive Honda Internavi Car Navigation System which intergrates Japanese GPS, mobile phone, reversing camera, audio, TV, DVD, CD etc on a touch screen and steering wheel control BUT all graphics and buttons are in Japanese script. Unfortunately the car didn't come with any instruction manuals. I want to know anything anyone else might know about the entire system, in English language please.

The audio system seems to rip CDS to a HDD.
The radio still receives a Japanese station
The TV picks up some local channels but only audio
The GPS still reads Japanese cities but is active, as if we are driving in Japan!

Plesae contact me if you might be able to help with providing English language instructions manuals, or information about how software might be updated to srilanka GPS and English instructions.

Cheers experts!

The relay for the a/c need to be checked.

check the speakers in the rear deck, in the rear hatch or trunk, often the two wires that come out of the speaker touch if that happens it will short out the speaker drivers in the radio most times no permanant damage will occur. separate the wires so they do not touch,or touch the metal speker base, that may not be the problem but its a start..

some power steering system is computer control. if you disconnect battery the control module have to be program.the control module uses vechicle speed sensor and steering wheel rotation sensor.to operate an actuator in the power steering pump to control pump pressure and steering assistance.

You need to disconnect the battery and the airbag diagnostic control module in the dash, do not remove the airbag until this is done, if it goes off you will have a really bad day.
