Becker Navigation Problem

Hi. Have just installed a Becker 7949. The unit seems unable to calibrate correctly. It can find a 3D fix once I reset the unit, and can tell me where I am on start-up, however it continues to say that I am on the same road throughout a complete journey. All gps and gyro funtions appear to be working correctly (and move with my journey) however I have noticed that the 'wheel' value never changes from zero I have also noticed a thin horizontal electrical interference 'pulse' type flash which regularly (every 10 seconds or so) flashes on screen. Is there something that I can do or should I send it back? Any advice welcome thanks.

There is a becker manual/ installation guide at the above url.
It is free to download in PDF format.
This may help solve the problem.

It seems like it may not be installed properly or your car electrical system is causing interfereence.

If this does not help write back please.

Dodge RB4 nav system problem


Here is the link to the user manual if you need it; http://www.rb4navigation.com/RB4-user-manual.pdf Do you have the navigation CD for the east coast?. The unit will not function without this cd being used initially to prime the system with data. (Page 69) Check page 114 and make sure the correct region is selected - if that is set on west coast it could be the root of the problem. Check page 116 - try recalibrating, then see what info is displayed. The time should be correct and steady, and check your correct position from a friend's nav system, see if what your unit is displaying is about right. If it is displaying no position, check in the middle of the screen where it says sat: 05/07. see how many satellites your unit thinks it can see - less than three and it won't function at all, 5+ is pretty much essential if you are moving. Where it says Fix:3 at the top left - what do you have on your unit? (check the next page for a description), this may tell us more about the problem. check if the time being displayed is correct - if not then the unit is looking at the wrong page in the almanac, and wont find anything if none of those items are right, then the prime suspect is the GPS antenna and it's connections and cable. These are the most likely thing to fail in a gps other than the power supply. Check all the connections and cables thoroughly, at the unit and at the antenna, if still no luck then a new antenna should solve the problem The distance pulse/going backwards problem is definitely either the sensor, the cable or the connections - couldn't find any info where this is, but my guess would be either; near the gearbox - the same place where the speedometer sensor/cable comes out, or direct from the vehicle computer as a composite of several sensors info, which would make the vehicle sensor array computer a prime suspect - if the same info is displayed anywhere else in the vehicle correctly (speedometer for instance) then the GPS unit or more likely the cable from the sensor array is the culprit. The distance pulse/ direction info should not prevent you from getting a position when not moving, although it would quite possibly cause a brain malfuction in the unit while moving, I think the unit would automatically choose the satellite info if the signal is ok though. recently the software support for this unit has been discontinued, and customer reviews are to be honest a lot less than great - rather than spending lots of money having this fixed or getting a new antenna etc, I would consider buying a replacement unit - please ask if you want advice on what to get Hope this helps - post back with details of the info on those screens discussed etc and we can hopefully come up with a definite problem before wildly replacing things :)

I need code to my radio becker de 7920 serial 55049487


Hi,

The best place to get the codes for these Becker units is here.

Just send a request via the contact form and they will email the code back to you. Cost I think is around £7.99 for Becker. I use them regularly as I repair radios and the site is one of the best around and always accurate.

Hope it helps. Thanks for using fixYa.

Because I changed from car battery, I lost my code for a Becker Indianapolis BE 7920 serial 45016322. Can somebody please give me the correct code?


Hi,

These codes are not available for free anywhere online. I suggest this site which is one of the few I know that provides guaranteed accurate codes for Becker units and they are by far the cheapest out there.

Hope it helps. Thanks for using FixYa.

Cda 7949 turns off/on by itself


Sounds like a lose wire in the harness either yellow, red or black. Pull radio and shake the wires around untill you find it or the face plate is lose.
