The latest version is v32, so if you’re on v28 then upgrading to this should sort the issues.
Some of the update images online and on eBay are heavily modified so I wouldn’t recommend using them, but you can download unmodified update images at:

However this will have the ==BMW== logo on boot. You can change this on Navtweak. Instructions at the link below, but basically keep the resolution the same as the original 400x234, 256-colour and saved as a BMP. I’ve just made a Rover logo one for mine, but scaled for the original 4x3 Bordmonitor. If you get stuck let me know as I only worked this all out a couple of weeks ago so it’s quite fresh in my mind so could knock up an MG logo screen if you wish
