Those with P880PRS or P800PRS

880 does... not sure how accurate it is, though. I think mine actually reads low on the headunit. Maybe by 1/2 a volt or so. Have yet to do real-time testing on it though.

 
It's not 100% accurate but it was pretty close when I used it.

I was using the diagnostic tool for VWs, and the measuring block I was in listed battery voltage, so for comparison reasons I put the voltage background on the 880, and there was a difference of about half a volt to a volt.

 
MIKE,

Slight OT...do you like your 860??? I am thinking of buying one...I have run into one that is extremely clean that I might get...would you be selling yours??

Thanks,

Mike

 
my 780 is accurate within 1 volt. multimeter reads within 1 volt of the head unit..

i think it's kinda vehicle dependant.

If I could wait, I'd wait for the 800 vs. buying the 880 today.
agreed.

When I did it on mine it said 16 v, and I was at around 13.5 lol.
that is a harness problem, not the unit, i had a harness that did the same.

860mp is a nice HU, but besides the pre-out voltage is not near the 880prs.

How is it a harness problem?

It means the pre-outs of the 860 were better than the 880. Tis all.
