Hey guys,

Quick question for you NAV guru's.

I have an 00 M5, i had a MK2 unit before, i just upgraded to an MK3 unit, with 3-1/63 V22 software i believe.

Anyways i hooked everything up, put the CD in, everything works, except when i clicked onto GPS navigation, it says "Please wait a moment" and never ends up doing anything.

I also was unable to get the cd out the first time, i had to wait for it to shut down then unplug the blue power connector and hit the eject button till it came out.

I always waited till it fully shut down, the light would stay on solid, then blink fast, which i assume it was writing to flash then turn off.

Under the OBC it shows my location, and under "emergency" it shows my current longitude/latitude.

Any help guys? Should i try upgrade to V25?

Should note, the first time i put the CD in, it said "please insert NAV CD"

Also if it makes any difference, i have no ECU in my car currently, it is being returned from powerchips, if that matters at all.

Thanks
Chris
