“Great service and a product that works. I had no success with the Porsche main dealer, but NaviMann sorted my satnav update on my 2015 Porsche 911 with little fuss. Would recommend”
“As the previous reviewer states, be aware that absolutely nothing appears to happen, when loading up the first two USB sticks. Do as the instructions say, count to 120 and reboot on both occasions. The video illustrates perfectly the procedure during map installation using the third USB stick. Also, do use the software update disc first, even if you have the latest firmware installed, the process requires the appropriate installation files, for this map update to 6.7.1, without them, you'll get an error code and failure to complete the upgrade. One final point, and I've no idea why, but the whole process only took about 90 minutes to complete and I'm certain I have a standard head unit installed!”
