  1. Hi David,

    I've been pointed in your direction by another member.

    My B9004 head unit is very similar to the TNS 510 & is showing an identical contact your dealer message after I disconnected the battery.

    I've read you other posts but my problem is the B9004 doesn't have an SD slot, only DVD & CD. The original maps DVD remains inside.

    The satnav packed up a while ago but I still getting radio & phone capability. Any ideas on how I can get these back?

    Many Thanks,

      Hi Nick

      sorry i cant help you. The file that gets corrupt in the Tns510 is a file called Loading.Kwi which is tbe Tns510's operating system and is only compatable with the Tns510

      OK thanks. Took it to indy garage who had it all day. Finally got it working by disconnecting battery for 30 min & leaving before reconnecting!

  3. Back in 2012 i purchased a set of the original leather upgrade. It was Plum in colour which matches my interior. It cost £570 from Toyota and is sourced from Greece. I borrowed upholstery tools and fitted them myself. The glue over the existing seat covers. You have to glue otherwise the covers do not take the contour of the seat and they flap about at the point behind your back. Beware because whatever you decide, you have to take into consideration of the "squib" airbags on the side of the seats. David
  4. I think i got mine in 2013 and works perfectly. If using in an auto model then you have to put it out of drive to unlock the doors David
