There are several different kinds of TomTom GPS units. Most of their units will run the average consumer between $90 and $160, depending on what model you choose.
According to customer reviews the TomTom is pereferred over the Garmin in most cases for cost reasons.
There is no annual fee for the mercedes navigation system but there is a cost to purchase and install the system. The general cost of the system is from $800-$1200 depending on the cost of installation. http://www.benzworld.org/forums/audio-telematics-forum/1361910-install-navigation-system-w211.html
This Question doesnt make sense, TomTom is public company - http://en.wikipedia.org/wiki/TomTom , http://www.tomtom.com
Garmin is the best GPS navigation system available at this time. Giant electronic retailers such as Best Buy offer advice on GPS systems. If you have an android smart phone, maps and navigation is available as a free product.
Probably approximately $100. There are used tomtom GPS devices for as low as $7 and as high as $210 on ebay. http://popular.ebay.com/consumer-electronics/tomtom-gps.htm
A tomtom gps for motorcycle, if you're not careful, can cost a pretty penny. Amazon for 495.00 used and a refurbished for 699.00 and that's the cheapest I've seen so far. http://www.amazon.com/TomTom-Rider-Navigator-Motorcycles-Scooters/dp/B000VB6VOC The highest I've seen is 799.95 at Gosale.com. So I don't think it'll get much lower than that.
The price of a TomTom GPS device can vary widely depending on the model and features. Basic models may start around $100, while more advanced units with additional features like live traffic updates and larger screens can cost between $200 to $300 or more. It's best to check the official TomTom website or retailers for current pricing and deals.

I think what your referring to is a GPS navigation system. These start at around eighty dollars and go up in price from there. They produce maps as you go by using satellite location.
When it comes to electronic stuff. I would take it to the pros. like the dealer or at lease someone who is certified. If not it may cost you dearly in the long run. I would call around for prices or search the web for local electronic shops near your area. different prices by towns and states.
I am not 100% certain I understand the question you have asked. In the UK: a 2 k.wh system would cost 8500 a 3 k.wh system would cost 10850 a 4 k.wh system would cost 12700 All solar in the UK is subject to 5% VAT.
this means that you probably bought it with no maps, this is an extra cost, you can buy them as an sd card or download them off the net (you have to pay for them)
