What's the difference between a Trinax and a Columbus, is Columbus newer units:confused:? I also noticed in some photo's columbus is wrote at the top of the unit and some are not..

I think.... emphasis on the think...... That Trinax refers to the VW variant and the Columbus is the Skoda unit. The badging must be down to different production runs.

Hope that helps.

trinax is 1Z0 035 680A

columbus is 3T0 035 680

both unit for Skoda

differences are:

in version 3T0 you will get:

- English male voice (female also available)

- Bluetooth audio (with compatible BT unit)

- clock on display

- progressive bar for volume in bottom of a screen

Using the firmware 940 posted on vwnavi on my version A (1Z0) unit, I have all the features posted by lala30 listed as for 3T0 unit. The male voice makes a refreshing change to the female one.

How do you mean bluetooth audio?

I think it might refer to support for AVDTP, allowing the streaming of audio from a BT compatible device to the HU.
