I think you are mistaken by the jack plug by handbrake, i dont have one ,only a i pod connection in glove box, then again i could be wrong as i have never looked at another dab. Anyway have had ours about 4weeks great value for money, a little slow at low revs, awful throttle responce, bad road noise, bad lights and i thought it was the drab edition due to the drab dashboard oh you cant see the stereo display because its so low and has no angle adjustment and no rear speakers (a total joke), interior plastics you just have to look at and they scratch oh and fuel consumption is worse than my evo7 .But get chrome/ali interior trim kits, upgrade your headlight bulbs turn the stereo up after you have fitted rear speakers, keep the revs over 3000 and its all
