Converting to cd/dvd to Navigation

[trx-racing]

I have a 2007 tahoe with the bose cd/dvd radio, if i wanted to put a navigation in it is at a simple plug n play. I dont want anything aftermarket thats going to look tacky. I would like the factory navigation but from what i see there about 1000.00
