I am looking to install my own auxiliary jack in my Suzuki sx4 crossover. Ive made the cable and connected everything as it should be. but its giving me an error when i turn the car on it just says "system update" Upon further research im seeing that this may be impossible for models with the build in GPS? ive disconnected my gps im just wondering if anybody can confirm that the port just isn't compatible for an aux because of the gps? and if its possible to fix without going and buying a new stereo? any help appreciated thankyou!
