Just to make sure everyone understands. There are a few differences between the Hualingan and the Dynavin. Pros and cons but I personally like the 7" screen vs. the 6.2. If you don't know what to get google the web for hualingan vs. Dynavin and decide.
Hualingan is plug and play if you don't have DSP or oem nav system. The unit works on these cars too but you have to add extra time for the install.
It comes with the plug and play harness (17 or 40 pin connector), take the MID and radio out and plug the new unit in. You have to cut the frame for Hualingan, that's 2 min job but that's the price you pay for the bigger screen.
I have it installed for a few weeks now and there is no way I will ever go back to the vintage oem radio.
