Sat Nav Using Bluetooth

My good old Garmin Zumo sat nav has given up and it is time to replace it .The problem I have is my old Garmin I used a 3mm plug connected to a set of ear plugs but I am now told the new sat nav do not have this facility,all the new sat nav use a Bluetooth connection .Here is the problem for and old git like me who does not understand all this tech stuff .I like the new Tom Tom rider Sat nav and they all use Bluetooth but the Bluetooth devices that the dealers are quoting are more expensive then the bloody sat nav .So if I budget for about £400 for a new sat nav and with the Bluetooth device that I am being quoting I am looking at about between £ 600 and £700 to replace my sat nav .Is this right or am I being taken for a ride .I not bothered about making any phone calls on my smart phone because I do not have a smartphone .I am not bother about an intercom .I just want it to operate my sat nav Can someone point me in the right direction here so I can get a new sat nav without taking out a mortgage .I just want a Bluetooth device to operate a sat nav .I have always had Garmin sat nav but it seems that theTom Tom rider is the sat nav to go for now ?.If I have to fork out £700 to replace my sat nav Ithink might have to go back to the good old road map !!!!!!!!!!!!!!!

 

Thanks everyone .I think I was being lead up the garden path by the dealer .Very grateful for all your advise .Make more sense .Think I will buy the TOM TOM V5 has suggested and also a Fodsport BT-S2 blue tooth .Thanks you all have just saved me a lot of money Great

 

Can someone recommend a reasonable priced Bluetooth to use with my old Garmin Zumo Sat Nav . Just need it for the sat nav . I do not want to talk to other people on it or make phone calls ,just solely for the sat nav ( and I do not have a smart phone )

 

Thanks , andypandy . the Shape Bluetooth looks like just what I was looking for .It should be compatible with the Garmin Zumo
