I have just bought a Kia 2005 Carnival wagon model KVII

I didn't have the code either.
I contacted the service department and was given the code

, I did have to give Kia the VIN Number of the car so that they could check they were giving me the correct code.
I should mension at this time you only get 3 attempts to insert the correct code or else ::crying::
My Kia has a Mobis AM/FM/CD Player, Model No. HM3700
The code for this model is 1812
To enter this code look at the channel selection numbers on the front of the radio unit. they are
1 2 3
4 5 6
The first number of the code is 1, so push the number 1 button once, if the number other than 1 appears in the screen above keep pressing the number one until the it cycles through the numbers until number 1 appears.
The Second number of the code is 8, so keep pushing the number 2 button until 8 appears next to the first number in the code.
The Third number of the code is 1, so push the number 3 button once, if the number other than 1 appears in the screen above keep pressing the number one until the it cycles through the numbers until number 1 appears next to the second number in the code.
The Forth number of the code is 2, so keep pushing the number 4 button until 2 appears next to the third number in the code.
This means that the code should now show on the screen above as 1812
Now that is done, now press the number 5 button to accept the code.
