Need Advice - Are Pioneer Head Units really bad?

[cornerbax]

Ok, here's the scoop. Don't want to bore anyone but i'm really getting frustrated at this point so I am hoping to get some help. Long story short, I have saved up for a system for a while. Ended up getting kicker amps, 4 channel/sub amps, kicker speakers/subs.

Went with the Pioneer AVH-P3100DVD after reading tons of reviews on several units and spending hours researching different units in my price range. I didn't really care about nav as I have a Garmin installed in my sunglass holder I use when I need which works great.

Anyway, I get my AVH-P3100 installed by guys who have been in biz over 15 years near me. I bought the unit through them. Everything was fine...for 2 days...that's when I started getting this high pitch engine noise during acceleration or any engine rev. It was really annoying. I've read this is can be a common issue with grounding, etc.

I also noticed when this engine noise started that my bluetooth was very distorted, crackling and full of static. The place I bought it from immediately talked about how "PIONEER" units are so much of a headache with this type of "engine/alternator whine" and that I would of been better off going with Kenwood or Pioneer with aftermarket amps. GEE, thanks for telling me AFTER THE FACT!! Anyway, I have gone OUT OF MY WAY because I searched that the resistors could of given out and that seems to be common with Pioneer HU's so I took it on for repair. They did replace the resistors as the article I read stated...so I thought I was good to go.

They get a brand new bluetooth as well at this place thinking the BT may of been bad. So I figure i'm gonna be good. Have a repaired Head Unit that I just GOT 2 weeks ago, and a brand new bluetooth. They go to install it and I have the SAME, EXACT PROBLEM! Same crackling of the bluetooth, same bluetooth distortion and same ENGINE WHINE! Once again, these guys are talking about how I should of gone with "KENWOOD OR ALPINE"....I've kept my cool thus far but im really pissed right now.

I feel I went way out of my way in not asking for a brand new unit on the spot and I took this unit 20 mins out of my way to get reapired to begin with, and went o pick it up! Not to mention had to go back each time for the uninstall and re-install...and I didn't ***** once...but now I'm really upset and am wondering how I should go about this.

These guys clearly havent' fixed the issue and whatever the repair shop "fixed" obviously wasn't the problem. Even if it was suggested here I should go with Kenwood or Alpine, I wouldn't want to go back to this shop....

Anyone have any thoughts, advice or suggestions on this? Any input would be really appreciated...especially at this point.
