MAIN FEATURES

 

Plug and Play cable for Volkswagen group cars with quadlock connectors to a standard ISO connector for fitting an aftermarket head unit.

 

Built in CANbus interface provides plug and play ignition feed.

 

This lead is required to fit an aftermarket stereo to your vehicle. It will adapt your vehicle’s wiring to a standard ISO connection which is used on the aftermarket unit. The one end will be the plug to receive the factory fitted audio loom and the other end will be ISO power and speaker blocks to fit into an after-market ISO female plug that comes from most after-market head units.

 

For a lot of modern vehicles come fitted with a single source factory radios which are CANBUS based. When you want to change these out for an after-market radio, you come up against the issue of them not having an ignition power supply in the factory audio harness for the new after-market radio to work with, as the new radio is dual source. Normally you would then buy an ISO adaptor, to which you would need to manually input your own ignition feed which requires knowledge, tools and labour to do. Well not anymore! This cables removes all of that as it includes a little CAN decoder box which will provide an ignition supply from the cars CAN bus data system when the key is in the accessory position, which makes it easy to fit and plug and play.

 

KEY ATTRIBUTES:

 

  • High impact ABS plastic of moulded connectors to provide the perfect fit
  • New GSXL wire provides more flexibility, handles more power and it is heat resistant
  • OEM quality of terminals provides the most secure connection between the terminals and the connectors
  • Includes CAN decoder box to provide ACC source
  • Plug and Play installation
  • Removes the requirement of knowledge, tools and labour for the installation

 

Please Note: This lead is not suitable for connecting Steering/Stalk controls on your car.
