Hi everyone,

I have a 2005 320 ci sport convertible with the MK4 sat nav unit (with freeview TV option), I bought a set of 2012 & 2013 DVD's both with V32 update CD's (all copies not OEM) from ebay. I updated my sat nav & all went OK, the unit shows SW-4 1/10. I drove the car for about 15 minutes with the 2013 DVD to see if all was working & everything seemed fine.

Today I drove my car & the unit keeps rebooting showing the M splash screen, finally it froze up & I got this very basic light blue coloured screen with basic controls. I turned off the unit & when I got home I removed the 2013 DVD & the system came back. I decided to test drive it with my OEM 2005 DVD I got with the car & it worked for about 5 min before rebooting again. I decide to drive without the GPS map on, just playing a music CD & it worked fine.

It seems to keep rebooting when accessing the DVD for GPS map functions.
Can anyone help me with this for a solution?

I read somewhere that SW-4/00 is the latest version & any number above this is a custom version.
Could this be the issue?

Thanks in advance.
