GROM Adapter is available now with 2 cable choices - VAGS (single din stereos) and VAGD (double din stereos) cable for dashboard mounting and VAG-T cable for trunk mounting.
Depending on where would you like to mount your adapter you can choose between those two choices, or we can supply you with both upon request.
Below are the pictures of VAGS cable (left), VAGD cable and VAG-T cable.


Pros of using VAG-T (trunk mounting) cable- No need to take out the stereo or disassemble the dashboard in order to gain access to the CD changer port
- Less time for an instalation work
Cons: - You will have to store your USB stick in the trunk
If you need to have 2 cables you can buy an additional cable hereWe also have the 6FT and 10FT extension cables hereNote for AUDI: In some AUDI vehicles, a solid 3-in-1 factory connector blocks access to the CD changer port.
The factory connector must be removed to gain access to the CD changer port. If that is your case you need to use AUDS harness that accepts the factory connector and plugs into the radio,
leaving the CD changer port open for proper use of any interface adapter or auxiliary input converter (including GROM-IPOD).
