My 2006 silverado head unit has some burnt out bulbs in it and i want to replace it, i did find that a friend has one out of his 2008 avalanche. it has the bose system and the auxilery in on the front. my question is... will the 2008 avalanche head unit work in my 2006 silverado?? I like the stock look and gives the un-honnest nothing to fuss over.
