Hehehe <evil laugh> Surely the Mk1 doesn't have a cell phone mute? (see FAQ) Oooh, I feel so deliciously evil after that! Sorry Tony, couldn't resist...!!

Seriously though, I'm not sure if it always starts up with the screen blanked. It doesn't seem to be blank when applying AC power, but the mute function definitely isn't working in tuner mode. I have Hijack v325 on the Mk1. I'll try upgrading to the latest version and if that makes no difference I'll reflash without Hijack just to make sure.

I'll check it again in the car tomorrow and make sure I'm reporting this correctly.

Failing that it might be the final push I need to get the Mk2 installed after all this time!!
