QUICK Question! (Swapping Head Unit)

Hi guys

Just in the middle of swapping my head unit and want to test that it is working before I connect everything back up really.

The instructions I have say the battery must be disconnected because of the air bag, so is it not safe to connect up the battery and test the head unit?

well i certainly never disconected the battery to swap stereos over

guess depends how much of the dash you got out i guess,

only had mine just over a week so i aint no expert on the supra

All done now. I disconnected it to be safe as the instructions said to do so. Its so fiddly getting the dash out but its all done OK now.

The only annoyance is that with my new head unit as soon as the ignition is started the aerial comes up no matter what setting you are on. Thinking about pulling it all out again and disconnecting the aerial

actually quick hijack, you know how you can buy a wiring harness for a supra so you dont need to cut wires when adding a aftermarket unit, is the jap one different to the uk, i know a shop that sell's the uk ones but told me the jap one maybe differnet???

lew

yes mate there i a special harness to buy which plugs directly into the wiring loom, about £10 from halfords

yes yes but is it the jap spec the same as the uk spec as halfords only sell uk spec ones

It's the same adapter for UK and Jap models.

Also, for future reference, you don't need to disconnect the battery when fitting a headunit. The only thing to be aware of is you need to plug back in the top strip containing the odo (there's three connectors I think) before turning on the ignition. If you don't, the airlight light will illuminate.

By doing this, you can test the headunit without having to put back all the rest of the dash.

For the aerial issue just put a switch somewhere on the aerial wire so that you can just put it up when you want to listen to the radio
