I'm looking to add Bluetooth to a 2002 x5 with nav and non-assist. I would like to have voice recognition for both phone and nav so I assumed I should go with a ulf module...

Then I was on the EAS website and they are selling a retrofit kit with a TCU. They claim that it has been programmed to handle voice recognition for both phone and nav:
eas - 714.369.8524 | BMW - Bluetooth Retrofit Kit for e53 X5

Is that possible? I thought a TCU could only handle phone VR... I'm thinking the info on the site is inaccurate but if it isn't I would like to go this route instead of installing a pairing button.

Any info would be appreciated...
