Paul Sir,
It's around $28xx - 29xx. I bought it at Mong Kok Computer Centre. You can compare the price before you buy it.
If you do not need WiFi and pure GPS + PPC, then you can choose P350. However, I prefer black color... and P350 is in white color... so, that's why I choose P550. Otherwise, P350 is relatively cheaper.
I have experience to use standalone GPS + standalone PPC too.. The GPS model is GPSlim 236 (this is the best one so far) and it has a latest model GPSlim 240 but I'd prefer GPSlim 236 at this moment. The PPC model is HP 4700. The screen is BIG and high resolution.
The issue is that you need to charge 2 devices in your car... If either one of the devices out of battery, then it becomes 'no use'. However, the speed to recognize the actual position (i.e. GPSlim 236) is faster than PPC with built-in GPS.
BTW, Mapking 10 is better than Mapking 7. P550 is good enough for me to use it as 汽車衛星導航.
