I was attempting to transition south west to north east below the Class B airspace when I visually saw the airport and 3 towers. This seemed odd given the MFD map position didn't agree with what I saw with regard to this particular airport and associated towers. I looked at the GPS that was driving the MFD and noticed a message indicating GPS loss of integrity. After checking for traffic; I immediately started a decent and in a direction to keep me out of a lower Class B shelf ahead. Almost simultaneous to this I opened foreflight on my phone to see if I had better reception and coverage for the Class B airspace. I did have proper coverage and got to an altitude I knew was below the Class B shelf. Once stabilized in altitude and direction; I reset the aircraft GPS to see if the loss of integrity signal would go away and it did.
SR22 pilot reported receiving incorrect GPS information.
