I've just installed GROM BT3 Integrated Bluetooth kit into a UK 2007 JEEP CHEROKEE KJ (LIBERTY)
The Grom appears to power up, as I can pair my phone to the bluetooth.
When I select the MODE button to select the CD Changer (CDC), I can hear a noise like a motor running, and then the Stereo reverts back to the previous mode (FM / AM Etc)
It's as if the Stereo cannot communicate successfully with the GROM.
I assume the Grom emulates the factory spec CD changer?
I've tried unplugging / reconnecting the cable between the GROM & Stereo, and also turning ignition on / off
Any ideas / advice?
