st170dan

hi guys, new FRS has had the st170 audio package fitted to it. however i have lost the use of the stereo stalk. anyone have any idea why this might not work? i have the 9009 h/u, 9009 sub and a jbl amp. also when i turn the radio on it says "no eq". my bass/treble settings are saved but radio stations aren't. any ideas? could the 2 problems be linked? id like to keep the set up as it is because the sub looks factory and prefer the look and is lighter than an mdf box so im not too bothered about the stalk - but it would be useful.
