Question about Pioneer AVIC-N3 GPS Receiver

Open Question

Wrong map location and incorrect compass reading. No gps signal but antenna says ok.

One day I was navigating to a friends house in Minneapolis. Anyways halfway there I just strayed way off course according to the map. I checked my gps connection and the antenna said ok but all the satellites were blacked out. I then noticed the compass was wrong also. I reset the system and that didnt do anything besides change my location from MN to Los Angeles California. Since there have been a few times where I must have gained a signal because it had changed my location to MN again but I went off course right away. I called Pioneer Tech support and they told me most likely a sensor was out in the hide away unit. I sent that off to be repaired right away and it came back and said everything was ok. Plugged it in and had the same problem yet. I have no way of checking my GPS antenna so I forked out the money and ordered one of those now but hasn't showed up yet. Is anyone familiar with this problem?

This may well be worse than you think!

I would suspect that the SIIRF chip or whichever chip is installed is damaged. This is common in many GPS It is not recommended to have them connected at the time of engine starting. An inline fuse must be used on hot wire to help prevent spiking if hard wired
If it is running on DC battery power the I would say battery is too low to recfeive satellites or that it does not have a clear view of the sky.
Usaing an external mouse type antenna usually gets a signal quickly providing it is positioned outside of vehicle with a good ground plane supplied ( center of bonnet or roof)
They should work in any car, they are not car specific. RESET button will not help if chip is damaged. Many second hand ones on ebay are there because they failed, they appear to work well because the screen lights up but they dont always connect!

n the system setup, under “UNITS” I set BEARING to “MAG” (magnetic). This will cause the unit to display course / bearing information in relation to the Magnetic North and match magnetic compass readings. It is not the same as True North! One has to be careful with this setting. There are a number of areas where the earth's magnetic field is locally disturbed, sometimes very significantly. Your GPS may not account for it. - again, under “UNITS” I set “METRIC”.


Bought a new Garmin Nuvi 40LMgive wrong direction from day one. do i need to take it back or is there some way i can correct it?

Get your money back and spend it on a good road map. I use the latest Philips navigator UK map, it never fails and keeps my old brain functioning.

I have a friend who uses a satellite navigation system. Having met up at a place, I knew he asked me how to get to somewhere local, I said go back the way you came and at the big church, turn left - I didn't see any church he said, I was following Sat Nav - that is the point without sat nav we become aware of what is around us so we learn our way, even in strange places, by looking at the sun we can work out whether we need to go east west, etc..

Get your money back and buy a map!

My navigation system in my 07 camry keeps telling me the address doesn't exist when I know it does. It won't find any address

If your GPS is not finding any address, then the most likely cause is that the wrong country map is loaded or the map is corrupted as finding an address does not rely on getting any satellite signals (your GPS should at least show your home location or the last known position on the 'correct' map): I suggest that you look at your specific GPS user manual to find how to check that you have the correct map loaded: if it is the case, then find the instruction on how to 'reset' your GPS as its software may be corrupted.
Hope it helps.


My error message says "A GPS-signal is not available now...."

Try hinging the antenna out from the back and angling it so the words FineDrive point up at the sky. It often takes 5 or more minutes to find the satellite, but it always finds it.

D3 navigation reads the wrong location of vehicle/radio

for some strange reason these units need the navigation/GPS antenna to get accurate range i had this problem with a install in Canada it said i was driving on water..........installed a GPS pioneer antenna and i was in my zone 2ft from actual location and no longer in the water ....this unit like all gets glitches from time to time and can reset sometimes on there own but because you are surrounded by water it is confused with actual location ....hope i was able to help you

Philips navigator MK8 Gps antenna is showing good but no update. Red light continualy flashes indicating wrong date and time. Can you help

Hi Johnsue05

pls. check the signal to noise ratio of the antenna signal. Sea page 23 and 24 of this manual:

If the signal to noise ratio is low, the GPS may have a bad antenna, cable connection or a defective antenna.

If you have performed a cold start (i.e. changed the backup batterie) you have to wait for 2-3 hours until der GPS has downloaded the almanach information.

Hope this helps.

Gps fail to reconize location

exit navigation, from the main menu select GPS reset, then restart navigation. if you do not get signals, you may have a failed antenna...

No gps signal 3 days now.

on the menu screen you should see exit at the top. when you click this you will get a screen to exit navigaiton as if to go to the mp3 player, from there click on setup and then gps reset.

if you have the genie lamp on the bottom left of the navigation screen then you have the old version, you can upgrade using these files and instructions:

install data

and the map data
