I'm not getting any sound with any source. I am not using amplifiers or anything like that as of yet. Does the blue/white wire have to be hooked up to the power ant to put out any sound at all?

I also have another issue, not all of the GPS options are availalbe for me to use, such as searching for addresses, as a matter of fact about 85% of the options i cant use.

the only thing i can do is get directions to banks, fast food, gas stations, and food chains that are with in the 10 mi area.

Also when i started up and installed the DVD info it wouldnt let me change the N3's time. Alot of the options and stuff are blocked off from me to being able to use

I thing your amp ic is gone (pal007b)

Put your parking brake on to get the rest of those menu options.

Does your car have a factory amplifier?

I have the same problem. I don't know what is wrong?

year make model of the vehicle would be helpful as well as any aftermarket equipment installed.

make sure you have the navi disk is in the player
