am i right in thinking that the columbus sat nav has a 7 digit postcode search or does it need new firmware to get this,ive got a dec 2010 unit to go into my octavia vrs when it turns up on sept 1st and iam hoping this has it already on it,any advice would be great

I'm sure you can type the post code into the city field

A December 2010 unit (mine was built late November 2010) is just after the V7 maps came out, so it should have 7 digit postcodes already on it, however some cars delivered in 2011 still did not have V7 maps installed! (V7 is the oldest version that will accept 7 digit postcodes)

If the unit does not have V7 maps installed then it is a pretty safe bet that the firmware will need updating also, as installing V7 maps on old firmwre will still not give you 7 digit postcode search.

Clear as mud now?

were do you get the latest version of the firmware from and anybody put me in the right direction for 2012 maps

just powerd it up at home and its defo got the 4 digit postcode on it,if i get a 2012 map disc does it up grade itself or does it need the new firmware aswell

New firmware needed separately from map disk sorry. Try here: http://www.my-gti.co...and-information

can anyone help me with this,or will i be able to take it to skoda to get this done as i dont want to brick my columbus,been told they will do a firmware up-grade and load latest maps on does this sound right

Skoda do not offer firmware upgrades, as when hooked up to their rig it will say the latest version is already installed. The only way is DIY, many have done it on factory fitted units without problem, most issues occur with retrofits purchased from Ebay.

my unit was not bought off ebay,does it have to be installed into the car to do the up-grade or can you do it on a bench running off a power supply,also anyone close ish to me facy do it as i dont want to damage the unit
