Hi everyone! I recently purchased a 2001 LX470. I have the stock Mark Levinson Radio and attempted to retrofit Bluetooth using the Grom BT-3. However, when I clicked CD nothing happened and I’m thinking it’s because my radio has an internal 6 CD changer with no plug/harness going back into the radio. Therefore, the radio isnt looking for the bluetooth when I click CD. Anyone run into this problem and know of a good solution? im wanting to keep factory head unit and just add bluetooth.
