hi guys i just recieved and installed my 310 yesterday. i encountered a problem with my navi. i noticed that when ever i turn on the car the gps freezes. when i remove it from the unit and put it back it will not power back on unless i do a soft reset. i was wondering if i am doing something wrong or its the unit. i called pioneer but did not have to time to wait for a tech to walk me through. any help or comment would be helpful. thank guys!

p.s. i am going to call pioneer back and see what they say about it.

Sounds like there might be an issue with the unit. I don't know what you could possibly be doing wrong to cause it to freeze.

yea i double checked the wiring and could not find any faults. i also checked the setting and everything seems good. the problems occures whenever i restart the car so its really bugging me. oh well until i have time to call pioneer i guess i'll just have to press the reset button everytime i start the car.

i just found this topic and i'm having the exact same issue with my avic u310bt. i called pioneer and they want me to send in the unit, they told me on the phone it sounds like a processor issue.

Hey Guys,

I just picked up the unit today and I'm having the exact same issue. I've noticed that leaving my ipod plugged in makes the unit freeze when starting the car. Try leaving any USB device unplugged and see if that works for you.

Either pioneer has a bunch of faulty units out there or it is a firmware bug.

another guy with the same issue. i just installed mine last night and it froze on me 3 out of the 5 times i turned the key on, regardless of a USB device. not a huge deal, but an annoyance. would be nice if it got resolved and it's just something we can download/update on the removable part with our computers.

well i talked to pioneer about the freezing with my unit and they think its a processor issue. i sent mine in and hopefully they'll get it fixed this week. i'll let you guys know how it turns out.

Since several people are having this problem, I thought it is something to do with Firmware, not hardware. Did you send whole unit, or just the NAV unit(Screen) ?

Sending whole unit would be PITA.

It seems the whole unit is rushed to market, and several people has several issues with this unit. I got my unit today, hooked on bench and started testing it. Some of the controls did not feel intuitive, but that's ok. The problem sofar I observed on bench are, it did not read couple of USB drives, even after format and kept giving me Error 23 on the screen.

So, I connected my iPhone, which is recognized and played fine. But funny thing is, when I turned off acc( Key turn off) while playing music from iPhone, and turned it on again, music start playing again which is good, but played like old worn out vinyl record, repeating the words. When I changed the source and went back again, it worked fine.

Unlike my Prius inbuilt Blue-tooth which paired very quickly with same phone, this one took too long to pair for the first time. Later it connected quickly. Vioce quality was not good, but I did not fiddle with settings yet.

Making all audio adjustment using the single joystick control kinda tricky, not easy like typical car audio systems, but I guess I will get used to it.

Also another thing, I thought I would be able to play music without the Screen, but I could not turn on the unit without the screen at all(unlike Eclipse unit).

Anyways, please let us know how it worked out for you after Pioneer fix.

Thanks

Hey yeah I'm having the same problem. It seems to lock up randomly. When I have the unit detached and switch it on, it does the same thing ...

The annoyance is when you hit reset with the unit attached in the car, it resets all my speaker settings

So if you want to avoid that, detach the face, then hit reset

Hopefully they'll release a fix for it, as us sending in all our units would suck ass

someone in the general forum said to do a reset without losing audio settings, hit the 'eject SD' button.

Did anyone sent the unit to Pioneer and got it back after fixes?

Also, wondering why this forum is so passive(esp for this unit)? Like hardly anyone responds, or give advise etc?

The unit is VERY new and there has never been a "U" series B4 so the user base if probably quite small at this time, as more ppl buy one and discover this site the responses will probably come quicker. I suspect that most of the long time members of this site all own that Z or F series so concentrate on those units most.

ok just installed my unit after gettting it back from pioneer. so far no freezing.

Here are suggestions from Pioneer to try to help with the freezing issue:

The U310BT has a on/off switch on top of the removable screen. It should always be in the Off Position(Unless out of the car) Off means it will turn on and off with the car.

1. Reset the unit with the small pin button on the right side of the face, then turn the key off for 20 seconds. .

If step 1 does not work...

2. Remove the face turn on and let the internal battery go dead. Turn the switch back to off and put the face back on the unit.

Did you send complete unit? or just the detachable screen?

Thanks

Here http://www.pioneer.eu/eur/content/support/support/upgrade/AVIC_F900BT_F700BT.html you can find firmware update for F310. It is the same unit, I think. There aren't hardware differences in between U310 and F310 I guess. If you decide to try this EU FW write it on new SD card in order to save old one in case of something goes wrong.

I checked the versions, it seems all unit that has been sold since July are having the same version.(Mine has same version at least). So there is nothing to update, unless you have a version older than 1.0001 as mentioned.

You can upgrade using SD card, but all the data including WinCE 5.0 OS is on the flash memory on the unit, not on the SD card. So, you would not be saving anything from old software/firmware.

Also, as I mentioned in some other post, Bluetooth module software is just a release candidate(RC3) not a final version it seems. No wondering so many people are having issues.

Hi Demetrius,

I am observing same issues with my Nav also. I see today Nav also froze, not just bluetooth.

Can you check and let us know what version of software you have for Nav and Bluetooth.

Menu--> settings--> Service Info

Currently I have 1.0001.

Can you also check for bluetooth and let us know?

Thanks

ok so the morning after installing the unit after it was repaired or updated at pioneer i snapped in screen and turned on the car and it was frozen and its been doing it all week i'm going to call pioneer tomorrow.

That is bad. I guess they did not even bother to test it. Just wondering if you got a chance to see what version of software you have on this unit.

Thanks

I have had zero problems with freezing and I use the unit for navigation and music extensively. However, I don't regularly use the Bluetooth functionality (only on long trips, and even then I turn it off when I'm done). This, paired with the many problems people have had with BT lead to believe it may be the root of the problem.

It may be worth a try to turn off BT in Settings before removing the face and then back on when you reattach. Could this solve the problem until there's a software update?

BTW, I haven't had any bluetooth hangs either. I have a 2G iPhone.

I am not sure why we would be removing screen at all, atleast I am not removing. I only removed to resets when it hung which is pretty every day.

Now, today I have something special, navigation showing that I was driving somewhere about 2-3 miles away. It is very clear day, full 10 satellites, and full signal strength as per Nav it self(in settings-->connections). It is not just not during initialization, but total 2.5 miles drive it is showing I am driving in correct direction but about 2.5 miles away over the road and cutting thru fields. So, I thought now I need to reset, used Eject SD card option and rebooted system. Nope, nothing changed, it still showing I am driving( not frozen) away. I took some snaps after stopping at our parking lot.

Finally, after few more resets, and by evening it picked up correct position!!?

Oh, I can not even believe, how did they even released such a half baked product, and how come I bought it.

I had the same problem occur once. I just kept driving for maybe half a mile (including several turns) and it eventually corrected itself. Not a good thing, though.

I had 2 more episodes of Nav unit flying me thru unknown place again. But this time, I just stopped at a shop for few minutes, then I selected "Go Home". Until this time, it was showing correct place I stopped. But after that it suddenly started showing unknown roads to me for directions, but I took usual highway. Initially thought may be it is not seeing Ramp. Nope, it kept showing I am flying somewhere else even after few miles on highway, and switched to another highway. GPS shows full signal with 9 satellites locked-in with full signal.

Since, last time reset did not help, this time I turned off the unit(while driving) and then un-docked the screen, and docked it again. After this, I got the Nav screen, and highway I was traveling was identified correctly.

Again, this morning, I took my daughter to class, and while coming back, I saw it is showing some unknown roads for a mile, later I went to GPS signal screen and saw more satellites lock in. After that it started showing correct location again.

I do not know what to think about these Pioneer guys, and saying they do not have any problems reported.
