having had trouble getting my stereo to power up its now sorted, thanks everyone for the info. but i have no sound. ive fitted stereo AND new speaker wiring ect just bypassing the oe loom. my question is should the bonus have an amplifier as standard . , if it has one. do the oe wires pass through an amp en route from the radio harness to the s[peakers? if so ill try wiring up the stereo/speakers using the std wiring
