Narrative:
In cruise; having just passed over ZZZ airport. Was navigating to fly through a wide gap in thunderstorms approximately 40 nm south of position. Noticed the avidyne multifunction display (mfd) flicker; followed immediately by the smell of electrical burning/arcing. Elected to turn 180 deg immediately and informed ATC my intention to land at ZZZ with priority handling. I had my copilot get the ATIS for landing information while I descended rapidly through the ovc layer. No fire; no smoke. Display remained on during descent; but smell continued. Due to altitude and short distance to ZZZ; I overshot airport and had to spiral back; all in IMC. Broke out of ovc on downwind to runway; saw runway and landed visually. Was able to taxi to the ramp and shut down without further incident. Call made to ZZZ tower as requested.in hindsight; I could have pulled the breaker for the mfd and relied on my GPS or ipad for navigation to ZZZ. The display continued to function without smoke; however; and I used it to locate the airport as I spiraled down in IMC.
