Hello Paul,
you're in a much better situation than me: it isn't just the radio which causes trouble...my "brake issue lamp" started to flash now 3 weeks ago but I don't get a date to repair it til 17.05. In this time I'm not availible so the next date will be 29.05....that mean I can't run my vehicle over 2 month...Polaris Service Germany told me also I have to contact my dealer, they are out. Now I got a box with both sensors and seals inside from my dealer and directly the bill about €160.-(roundabout $170.-, the price in USA is $80.-). I directly called them if I'm allowed to install the sensors by myself but the answer made me totally pissed off: in case I install them by myself the warrenty will be deleted.I wait now til 29.05. if all my open points are sucsessfully closed, otherwise I'll visit my lawer.
My opinion is: a great idea behind this vehicle but the dealers are completely overwhelmed with this new product...it's a pitty.
@mondanai, not sure why you have to pay for warranty parts!?!?
