Hi Guys,

After many trials, I've been able to fit my RNS-E in my A4.
However, I would like to know about calibration.

I set the parameters under STG 56 adaaption 10 to:

Channel 001 (Tires) - 1964
Channel 002 (GALA) - 45


I checked the speed pulse, and it is present, and registering.

I presume that channel 2 is for noise, and should have no bearing on this
My wheels are 235/45 17's.

Currently, looking at the map, my car is physically further ahead than the map.

Do these units self-calibrate, and if so, I presume this will get better with more distance?.
Is there a switch to enable calibration?
The engineering mode says learning is on, but I'm not sure I trust it.


Thanks,
Ray :x

Mine took about 2 weeks commuting to work before it's position and orientation were accurate. Still struggles first thing some mornings while the GPS is still acquiring the satellites because there's lots of tight turns near home and the gyro isn't accurate enough. 110 degree turns become 80 degree turns and it thinks I've taken the wrong turning.

Normally, it should take a couple of miles to self-calibrate.

The RNS uses the GPS positions to calculate what size tires and which type speed signal (abs/gala) is used.

Please check the following data with VAG-COM:

go to

STG 56 or 37 (Radio-/Navigationssystem)
STG Function 10

-> Channel 001
Use this table, and use the number of the corresponding tire-size:

1790 - 145/80 R14 (sumer tires)
1815 - 165/65 R15 (sumer tires)
1803 - 175/60 R15 (sumer tires)
1806 - 185/50 R16 (sumer tires)
1935 - 195/65 R15 (sumer tires)
1910 - 205/60 R15 (sumer tires)
1930 - 205/55 R16 (sumer tires)
1818 - 205/40 ZR17 (sumer tires)
1960 - 215/55 R16 (sumer tires)
2060 - 225/60 R16 (sumer tires)
1930 - 225/45 R17 (sumer tires)
2074 - 225/55 R17 (sumer tires)
1943 - 225/40 ZR18 (sumer tires)
1960 - 235/50 R16 (sumer tires)
1964 - 235/45 R17 (sumer tires)
1967 - 235/40 ZR18 (sumer tires)
2065 - 245/45 R18 (sumer tires)
2065 - 245/45 ZR18 (sumer tires)
1940 - 255/40 R17 (sumer tires)
1937 - 255/35 R18 (sumer tires)
1937 - 255/35 ZR18 (sumer tires)
2016 - 255/40 ZR18 (sumer tires)
2016 - 255/35 ZR19 (sumer tires)
2092 - 255/35 ZR20 (sumer tires)

1775 - 155/65 R15 (winter tires)
1895 - 185/65 R15 (winter tires)
1935 - 195/65 R15 (winter tires)
1930 - 205/55 R16 (winter tires)
1960 - 215/55 R16 (winter tires)
2092 - 215/65 R16 (winter tires)
2060 - 225/60 R16 (winter tires)
1930 - 225/45 R17 (winter tires)
2070 - 225/55 R17 (winter tires)
1940 - 225/40 R18 (winter tires)
2010 - 225/45 R18 (winter tires)
2040 - 235/45 R18 (winter tires)
2114 - 235/50 R18 (winter tires)
1940 - 255/40 R17 (winter tires)

-> Channel 002
Use the value 0 (zero) for auto calibration.
If it this doesn't work out, try the value 45 for Audi A4 or 43 for Audi A3.

Good luck,
tony

One more thing: make sure you're RNS System is connected to the continue power (not accessory power).. The navigation must power off by a Canbus Signal (when you pull the key out of the ignition, the system will auto shutdown).

If you disconnect the whole unit by cutting the power all the calibration data will be lost.. So it has to re-calibrate every time you start your car.

Regards,
tony

in some cases, i think you just have to live with it being screwed up the 1st few miles..

mine starts off screwed up every day, because my drive way is pretty long and is parallel to a major street that is close by..

my position is right on, until i pull in my driveway, at which point it 'snaps' over to the major street.. so when i leave my place, it thinks i am on the major road instead of my driveway, but after a mile or 2 it figures it out..

I do have same problem, that my RNS-E does not work from the first kilometer.
Is this problem also known in factory fittet RNS-E systems?
