I recently purchased a gta 1000 off ebay,,according to the manual, i should be able to activate the audio boost and surface elimination. when booting up the detector i do see those modes (it shows all modes when first firing up) but when i go through the select modes,,the last mode i can access is the audio mode. when i push select it doesnt go to the other two modes. are the early gta 1000 without those modes?but the software is there. thanks. other then that the machine works great
