Hi, i recently installed a Head Unit in my car which i purchased from www.tradesolution.hk i then had to update the software on the headunit so my new Amplifier and Sub Woofer would work with the head unit. I'm trying to get iGO8 working with the head unit but when i put the SD card in the GPS SD slot it loads for a split second and gives me a INIT API error, does anyone know why this is happening and what i can do? When i put the gps sd card from the website they said it was plug and play, but its not working.

thanks kindly, Trent
