I believe this unit was originally priced when a new model around the £150 mark about three years ago? I found a brand new Navman F10 on eBay for £59 + delivery which arrived the next day.
I then came across the brand Navman which overall seemed to carry enough favourable reviews across their range.
Initially based upon personal recommendation I looked at buying a Garmin or a TomTom but even at sale prices I was looking at £100+ or so. I wanted a portable car sat nav for some European travel but during these hard pressed times, I didn't want to spend a fortune.
