So, I have just installed a range rover oem Bluetooth kit into my 03 (ie a BMW ulf with a rr specific loom, pairing button etc). It's a 13th gen module judging by the part number, and the wire colours in the 12 pin white connector matched up the the car. It all works fine to start with, pairing, phone book, etc. if I turn the car off and on, again, it all boots up ok. However, if I leave the car for a couple of hours, when I return, the computer does not boot up. I get the orange light showing the radio is on, but no splash screen or anything. If I pull the fuse for the computer, and put it back in, it all starts up fine. Anyone have any ideas what's going on?

Thanks

By the way, I am running a mk4 nav unit with v32 software.....

I suppose if it appears on the nav screen, and the microphone works, and you can hear people talking through the speakers - it's all wired in correctly.

Other than that..not sure - faulty unit ?

Does the same thing happen if you unplug the ULF.........?

Hmm, annoying as I have to wait an hour or so for the fault to replicate itself... I will try unplugging the ulf tomorrow night, and see if that cures it...
