1. WinCE kernel GPS---Those GPS units are all from Shenzhen China, so you might want to know what is the cost of each GPS. They are really cheap. such as this factory in shenzhen(www.szelebest.com) probably provides quite a lot of units to NZ. So for 100 unit of 7 inch unit, it will be 500RMB/unit. so it will be around 100NZD. for 100 unit of 5 inch GPS, it will be 400RMB/unit(around 80NZD/unit). for 100 unit of 4.3 inch GPS, it will be 350RMB(around 70NZD/unit). for 100 unit of 3.5 inch GPS, it will be 300RMB/unit(around 60NZD/unit. You might think I make up those figures. you can send an email to www.szelebest.com and ask for a quote. if you order more, the price will be cheaper. 100 units to 500 units, the price of same unit will be similar. The quote I give here is about 1 year old. So i am sure the current price is cheaper.
But you might say wait a minute, those sellers still need to pay for freight fee and import tax. yes. but shipping from China to NZ is cheap. DHL or UPS from Hong Kong to New Zealand can be 50RMB/kg to 60RMB/kg. So 50 units via DHL only cost around 1200RMB(it is around 240NZD). If you get a quote from DHL, it will be expensive because you are an individual customer. but there are a lot of agents in shenzhen or HK, they collect freights and help you to obtain better rate from DHL or UPS. Because those agents daily freight can be very large, more than 1000kg, it will be easy for them to get a better rate from DHL or UPS. so 10NZD/KG from HK to new zealand is common. As long as it is not christman period, this price is always similar. So how about import tax. Just one example, 100 units might cost 8000NZD. But the invoice only claims 1000NZD. so importer just need to pay 125NZD for tax. But there are many ways to bypass the custom system.
So let us calculate the total cost for 100 units of 7 inch GPS(100NZD per unit). 10000NZD(payment to the factory)+450NZD(DHL fee)+120NZD(tax)=10570NZD. so cost of each unit will be 105.70NZD. So you might cry, the price in trademe is 200NZD, 300NZD or even more! Oh I still have many maps and GPS navigation system.
So for iGO, there are so many iGO copies in the internet now. you can download with any problem, such as GPSUXdergXound. You can ask the factory in shenzhen to install for you. Those factories can install tomtom/garmin/iGO(all are free, if they want to charge you on software when asking a quote, just answer that I know GPS software are illegal copies so.....they will install for you finally withouth extra charge)
So you can calculate the cost of 5.0/4.3/3.5 inch GPS units. Well, I can not say those units are bad, but I am quite sure the hardware quality can not be as good as tomtom/garmin. So I can not give a judgement/suggestion when you need to spend around 200NZD on 4.3 inch unit, but I am sure 50% or more of your payment is the profit. So just click active sellers in trademe and check their feedbacks. you can almost calculate their income in the past. It is not a bad business. 50% or more profit.!
well if feedbacks are good here, I will post more inside stories here.
