Looks like yours is slightly older than Lee's but has been updated at some point (K rather than P in the software version) so same applies as I said to Lee in terms of process

Have a read of the link I posted and if it sounds like too much aggro go no further!

I'm down in the South East and have all the necessary resources but it's not something you can readily put together as a postal package!

On a side note.. Any sign of a process for the 3G+ maps yet?

Yep, looking do-able but not tested by me. Will drop you a line when at home with links of interest :)

Well the cost of my update would have been £445 !!! I told them I'd think about it.... Maybe I will try Adrian's method. Looks long winded and I'd have to buy a battery charger too that I'd probably never use again. :-(

Maybe a trip over to the South-East would cost me a quarter of the update cost in fuel and even slip Adrian a few quid for his time and trouble?
