Love the deck. Maestro rr kit in my tacoma. Steering wheel controls work great with radio,cd sat everything. The isse i come into is if i start navigation i cant use steering wheel controls to change station or whatever only volume works. I cancel navigation route and still same issue. If i turn deck off then back on i regain all controls as normal. Is this a firmware issue or issue with the hatdware in deck

Thank you

is there anything else connect like USB for carplay or android auto???

Carplay was connected at time this was goin on. Manual controls on deck worked at the time navigation was on. Ill try to have carplay undone and try
