Pioneer F700BT - 5.8 in. Car GPS Receiver

So I installed my 700BT about a 2 months ago and let me tell you that this is the last Pioneer Navigation I will EVER buy.
Where to start with the issues..............there are so many lol.

After I installed the unit I did the 2.0 update and went out to test how the GPS worked so I punched in a buddys address and off I went. About a half mile down the road it resets, I'm thinking this isnt normal so I continue on my way. After it FINALLY boots back up it keeps saying Satellite lost..........how is that possible when there is not a cloud in the sky, no trees or houses around me.....its an open area AND the antenna is on the roof. I get home and recheck all my connections and very thing is fine, I put it all back together and give it another shot.............wouldnt you know it the thing worked lol.

On to about a week later, the same thing starts happening this time it just kept rebooting. I figure the antenna might be bad so I ordered a new one, but no go...issue even with the new antenna. I go on here and learn that this is a common issue and I deleted a few files as stated in a few threads..............BAM it worked, for about 2 days before it started AGAIN! Now it will navigate for all of a few minutes before it stops responding.

On to issue #2..........Thumbdrives and hard drives are like Kryptonite. I plug in a thumbdrive and it works until I shutoff the car and restart it. When I shut the car off and turn it back on it does not recognize the drives, I have to unplug and replug it in for it to be recognized. I have tried all my thumbdrives which are Sony, Kingston, and Sandisk all different sizes, all of em do it.

Issue #3, I turn the car on let the system boot and guess what..................NO SOUND lol, not even the touch tone sounds, no music from CD's or from drives, but wait it gets better.... the AM/FM radio work fine lol. I have to shut the car off and restart it for the unit to fully work.

Here is a funny side note, my neighbor bought the 900 and it is doing the same thing with thumb drives, not having sound, but now it wont even stay on for more than 10 minutes when the GPS is on all it does is reboot.

I called Pioneer and they tell me to send the unit in for repair, well wouldnt you know it they could not duplicate the problems, figures . They reset it to factory and sent it back to me.............do I even have to say what happened when I got it back? The same issues, I called Pioneer yet AGAIN and I was not nice this time because I spent good money on this unit and it does not work even AFTER sending it out to them. The Customer service rep told me it was an installation issue.......ummmm NO, I know for a fact that it is not an installation issue, the symptoms do not fit their diagnosis. I have been installing car audio for over 10 years and I had 3 other installed check it and all is good and I'm also MECP certified and do this for a living. The unit is not hacked in anyway not hardware or software. So they wanted me to send it out for repair again, which I refused to do, at this point if I cant get this fixed on my own I will just chuck it. I heard rumbling about how bad Pioneer units are, but this is my first one for personal use, I have installed many of them and honestly alot of them came back with similar issues but I figured it was a bad batch or something so I went against my better judgment and picked one up...............big mistake, I should have stayed with the Kenwood. Never in my life did I think Pioneer would release such a inferior product.

I'm hoping someone on here can shine some light on how to fix these issues, because Pioneer has been ZERO help.
