Hi,

Thanks for the suggestion. in the satnav menu it shows 4-1/91 which is V30 "firmware" I believe. In the "engineer" menu under the "navi" option the OS version shows as 0910.

What antenna piece do I need to look out for on ebay and how do I get to it in the boot (removing the HK "sub"?) Am happy to remove the "upholstery" in the boot as had to do that before when gaining access to the stack to find the bt passcode plus to use navcoder.

Thanks in advance.

Darren
