TomTom- No GPS Signal 2019 | Week Number Roll-Over | TIMER Reset 00.00 | Error-"You cannot use this map"

TomTom Start 52 speed display fluctuations

Recently, when cruising at a steady speed the speed displayed jumps up then drops back down: for example - 40 mph displayed - rises momentarily to 48 mph, then drops back to a steady 40 mph. Is this likely to be a fault with the SatNav or interference with the GPS signal caused by buildings or trees?

If it is a fault, can anyone suggest how to rectify it?

    Try a drum reset on your Satnav
    Press the On button about 20seconds til you her the drumsound and the device starts again.
