I just got the Z140 installed in a BMW X5. So far I like the unit very much.
A couple of features issues I'd like some help with:
1. Can you reprogram the steering wheel control up/down to change stored stations rather than manual frequency change, hitting ^ gives you 92.3, 92.5, 92.7, etc. instead of 92.3 (Channel 1), 94.1 (Channel 2), 99.7 (Channel 3).
2. If you don't have a MODE button on steering wheel control can you reprogram another button. My X5 has a Voice Call button that is not working.
Thanks for any feedback.
