Hey,

I am looking to swap my MIB3 unit with a SH MIB3 unit due to corrupt maps that cannot be fixed.

Current unit OEM code: 3V0 035 816 B ( PREH unit )

I noticed the following units have been installed on several other models as well ( PREH units as well ):

3V0 035 816 [A | B | C | D | E | F | G | H | G | K | L | M | N | O | P | Q]

3V0 035 820 [A | B | C | D | E | F | G | H | G | K | L | M | N | O | P | Q]

I have 2 questions:

1. Unit having OEM code starting with 3V0 035 820 are compatible with my car as well?

2. Newer units (mostly starting from the letter H) are JOYNEXT units. Are they compatible or I should stick with whatever PREH unit I can get?

Thanks in advance!

There's an audio part of the forum, it's probably worth posting there as well.

There are are several helpful members with knowledge of SW updates and repairs.
