I am advertising this system for a friend who has had to finish driving through a Stroke/Heart attack. almost 12 months ago he purchased the Pioneer AVIC F130 Sat Nav system which is specifically made for large vehicles, By that I mean you enter dimensions weight, axles, Height etc, I can confirm just how good this system is as it is the same one I use. The system has many thousands of campsites etc already loaded in and it is extremely easy to add further POI's either large files or single POI's. This unit needs attaching to a Pioneer AVH**** Multimedia system The system does countless functions, if anyone wants to ask a question about it please ask away as I have used mine for just over a year now. He paid £560 for this system and they are wanting £350 for it. there is existing features that cost which will obviously come with it ie radar warnings TMC etc. Also there is a an AVH 3300BT Multimedia system available which is a Double Din CD/DVD/Bluetooth/MP3/Ipod/Iphone connectable This unit cost £490 and is for sale at £250 including postage. Both are 100% condition and working fine.
