I have a 54-registered Honda Accord with built in Satnav. I travel to Spain, via France, every year and have found that the system does not take into account the many new roads and changes. The Navtech onboard system, disc APN2-34102 ver.2.05 needs up dating. I have spoken to the main Honda Agents who quote an incredible £148.00. I can buy a new standalone system for a fraction of the price. Indeed Tesco is offering Satnav today at just £20. I would like to update my onboard system and would be grateful for any guidance for a reliable supplier.
