So i bought a 2010 Chevy last year with a 6.2L Gas, its basically fully loaded, but has almost a basic stereo just the one with the CD/MP3 reader, has steering wheel controls, blue tooth, onstar, and the standard heater controls. I was looking for some upgrades for my stereo, thinking an aftermarket but after all the mods i have to buy its not going to be cheap so i found something like this
Chevrolet Tahoe Silverado DVD GPS Navigation In-dash on eBay.ca (item 150559705665 end time 07-May-11 23:10:13 EDT), any one else ever try this deck, it looks like a factory one but I'm not sure.

(well i answered my own question about the stereo it does not work with the factory blue tooth so i don't want it, lose the steering wheel controls for that option so ill keep hunting)

As well was thinking about buying something like this Heater A/C Control CHevrolet Silverado 2007 - 2009 NEW on eBay.ca (item 140516588280 end time 25-May-11 11:22:23 EDT)
To change my heater controls,. does any one know if this would just plug in or will it not work with my current controls. This is what currently installed Heater A/C Controls Chevrolet Silverado 07 08 09 New OE on eBay.ca (item 290478367214 end time 19-May-11 10:31:36 EDT), that's the first few upgrades I'm looking at doing, as well hopefully better speakers and some sort of sub,
