Hi all,

 

I buy 2 rear camera on ebay (one big and one small circle cam); I try the big camera on rear input with blue 12v cable (for amplifier, from AVIC). The camera work perfect but I remove it because it is so big.

 

One week after, when i received the small camera, I installed it on rear with 12v form the car and cable Input rear from AVIC. Image appear but so trouble (like PAL NTSC incompatibility).

 

What problem? Can I change PAL NTSC option on avic?

 

I retry the big camera but same matter??????

I verify power polarity, it correct.

I remove long RCA cable and I try directly on avic but same.

2 Camera work perfectly on TV.

 

The only small difference between the old and the new installation is the power cable.

re,

 

I try external dvd player on AV1 input, picture appear trouble 5sec and after all are ok.

 

A cant chose EXT on AV2 and EXT-1, EXT-2 don't appea on AV source.

 

Please help.
