Hey Guys.. i have a Daewoo Lanos 98 Model...
I just got a headunit off a mate which wors in his car but when i connect it to mine it doesnt power up.. i have use d awiring harness that matches the original daewoo lanos and have connected all the wires together.. i have used a amp tester to check that all connections are true and which they are... i can't see where there is a problem.. does anybody have any ideas?????
I htought it might be the earth but have connected it exactlly the same as the previous tape deck??

First thing I would do is to take the HU to the battery...connect the ACC and Battery wires to the + of the battery and the ground directly to the - of the battery to ensure the HU does work...that;s the easiest. Next ensure the HU is grounded good under the dash...a bare metal connection is far better than using the stock grounding wire...how knows how long that ground wire is.

we need to start simple first, and work our way up... Did you have both a +12v constant, and a +12v switched? Did you check the fuses? What kind of radio is it?

A bench test would take 3 min.. I have never really understood why people would charge for that.. I always saw it as a great way to help a customer.
so you have checked these wires with a voltmeter? then we can move on. I would start testing the speakers impedences(ohms) next
