Default [Q] Headunit running Froyo

Bought this Head unit off ebay and of course everything but the wifi works.
ebay item number 111282445501

I plug in the dongle and when I go into settings it searches and then times out. never finds any networks.

So I'm thinking its the drivers I look up the dongle manufactures and its realtek which i know is a popular one and found the following site with downloadable zip files only problem is I dont know how to get them on the unit. I can drop the files to an sd card and open the files with file explorer but not sure which file to open and how to do it. I am in way over my head.


realtek.com.tw/downloads/downloadsView.aspx?Langid=1&PNid=48&PFid=48&Level= 5&Conn=4&DownTypeID=3&GetDown=false&Downloads=true #RTL8188CUS

Any suggestions or help would be awesome.
