Sorry to say that the aftermarket unit would likely be the best option for your vehicle. The newer OEM units after 2005 are not a self-contained system and use network connections that don't exist in your Tahoe. The navigation units in them also were not integrated with the stereo, they were essentially a modified Garman unit in a custom application. When they switched to the newer modular designs with the receiver in one place and the display in the dash, they also added more networking. Also, all of the OEM radios installed from about 2002 to now are VIN locked while the aftermarket units are not, so even getting one from a 05 is a hassle to install without a factory level scan tool or dealer access. Also be aware that you can get units like yours with Bluetooth added, but in most cases, it isn't a two-way system, they only allow you to stream audio to them, they won't operate as a hands-free device. GM and others made things difficult at best and they have been just getting more complex over the years.
