Thanks Paul, just found one at our local kmart.. Should do the job fine!

G'day, we use a 2008 Kia Grand Carnival 6cyl 2.8L fitted with 2,000kg tow bar. Towed over 2,500km over 12 months, happy to sit on 110km/h if conditions are good. Fuel is ~16l/100km (Would improve if I slowed down!!). No problems (yet) retreiving.. this was my biggest worry not being a 4x4.

G'day, found a free windows mobile program with anchor alarm which I can confirm works ok on a HDC HD2.. not as good as above but has other features also..
