Calling E46 In car entertainment specialists

[Ray Singh]

Many thanks for reading.

I have a Alpina B3 3.3 based on a E46 BMW. Its got a widescreen headunit fitted and this was working fine.
I noticed that the sat nav wasnt working and bought a second hand unit from M3 cutters. This arrived and the system worked well. I even installed an Alpina splashscreen which looked really nice.

I then bought a hybrid tv tuner from ebay and installed this today. It didnt seem to work, i.e. no output at all on the screen, so i replaced the old one back thinking that it would just go back to my original set up.

To my horror the screen has stayed blank. The whole screen appears to go a little lighter when i put the key in, but i get nothing else at all.
The radio works, but without any display.

I felt like i was getting all the little niggles on my car sorted and now i have gone back 20 steps. Any help appreciated.

Thanks
